Materials and SuppliesWhen shopping, its important to locate your correct underwire size. If this is your first bra, I highly

recommend buying underwires in the size you think you are and then one size up and one size

down. Just 1/4 could make a massive difference in comfort. You might be surprised by what ends up

being comfortable. (And yes, I was wearing the wrong size underwire for many years so I can testify.)

What you choose for your bra fabric depends on your experience, and what kind of support you need

or want. Those of you with experience in bramaking or who have a different pattern than the ones I

chose may want to branch out and try some new fabrics or techniques.

FOR THE CUPS AND CRADLEThe patterns we are making require some kind of stable cup fabric that does not stretch. If you want

to use a stretch lace, lycra, or anything with spandex, youll have to either line or interface the cup in

some way. The bridge will always need to be lined or interfaced, unless you are using a very stable

fabric.

Traditional bra fabrics:Duoplex, Simplex, bonded or fused tricot.Of these, (I personally like

Simplex, which has a nice drape and is very soft on the skin.) These are all satin-y tricot/raschel

fabrics and are easy to sew.

Natural fibers:Woven cottons or silk satin like acharmeusea beautiful bra fabric. Keep in mind

that woven cottons dont tend to be t-shirt-friendly (fabrics stick to it) and sometimes the seams wont

lay as smoothly. I love silk bras and I take good care of them, but they are not sweat-stain-friendly

(living in Texas, ask how I know!).

Lace:A rigid lace made for lingerie is perfect as a cup fabric.Lingerie stretch lacesare another

option and usually more widely available.Sewing stretch laces do require a little bit of

experience in fitting.They will also need a stable lining as I mentioned above. Some of you may

want to experiment with using lace or some kind of decorative mesh on the outside of your cups or

cradle. There are many different ways to use it.


2/62

For linings:15 denier tricot or 40 denier tricot. In some places these fabrics are simply called

tricot or net. These are very useful fabrics to have around in bramaking. The 15 is very sheer and

stretches just a little. The 40 is more opaque. Some of the kits will include a bit of this for lining. I like

to stash some in neutral colors because I use it everywhere. It is very useful as a stable lining for thebridge and cradle area (and almost all my RTW bras use it for this). Some bramakers like to use

powernet for lining.

Instead of lining, you could also stabilize a fabric withfusible tricot interfacing, often used for knits.

Look for something that can be fused at a cooler setting on your iron.

Left to right: 40 denier tricot, 15 denier tricot, fusible interfacing

FOR THE BAND/WINGSIdeally, your band should use a fabric with about 50% stretch and good rebound.

Powermesh/powernet:Powermesh comes in many weights and qualities. Some women will need a

heavier weight powermesh. I like medium weights if I can find them. They are soft and drape well but

strong enough. Very lightweight powermeshes are useful as a lining for stretchier band fabrics but


3/62

are really only good for the lightest of bras or even knickers. (The ladyshorts photo in my sidebar is

made from a lightweight printed powermesh.)

left to right: heavy, med, lightweight powermesh

Lycra:These can be good band fabrics but check the descriptions as some lycras may be too

lightweight or too stretchy for you. Youll have more options in color choices, which is probably why

folks making bras tend to use lycra instead of powernet.

For now, try to avoid using jersey as your band fabric. This is something you might want to try later

but jerseys often get narrower as they are stretched and are quick to lose their elasticity. If you have

allergies or need/want a natural fiber bra, you can try making a band from woven materials, but you

will have to experiment with the patterns band length to find a comfortable wearing ease.

A note about lycra for those who are new to sewing lingerie or swimwear:For the most part, fabricslabeled lycra by lingerie, swim or dance fabric shops are tricot and raschel knits made with nylon

(sometimes polyester) with spandex for elasticity. The quality and weights of lingerie lycras will vary.

Some of them will have a 4-way stretch, some 2-way. Sometimes suppliers may sell an uber-soft

microfiber lycra, other times youll end up with something that looks more like shiny 80s swimsuit

fabric. I try to read the descriptions carefully if there are any.

ABOUT BRA KITS

With a lot of kits, you will need to order underwires separately. Be sure to read their descriptions.

Also, many kits seem to be short on strap elastic, so consider ordering a bit extra. For my bras, I

need about 114,3 cm of strap elastic and I have a short shoulder-to-bust length. The Bra-makers

Supply kits assume you are making the fabric strap in their patterns so they really dont include much

strap elastic at all.

Note that Merckwaerdigh and Elingeria kits are often entirely stretch fabrics so you will need linings

of some sort.

Find your band size


7/62

To find your band size, measure yourself snuglyaround your ribcage, right under the breasts. It

helps to breathe in and halfway out, then measure.This measurement or closest even band number

upisyour band measurement.

If this sounds too small to you, try measuring yourhigh bust, just above your breasts and going

under your arms. The closest even number to this would be your band. Basically, your band needs to

be close to the width of your chest as if your breast tissue werent there!

My underbust is 29/74cm and and my high bust width is 31.5, and I usually use a 32 band.

Sometimes I go down to a 30 in a bra with really stretchy materials. In European sizing, I use a 75.

Note: If your pattern tells you to add four/five inches to get to your band measurement, I recommend

that you ignore it!When making a custom bra, you can always adjust the band for comfort by

lengthening or shortening later, and most likely you will do this anyway for different stretch fabrics.

Underwire fitDo you know which underwire fits you best? The bra patterns Ive suggested all use a regular length

underwire, but in the future some of you may want to explore using a shorter or longer one,

depending on your support or comfort desires. Its good to experiment!


8/62

I found my best wire size by comparing 3 sizes of wires, going one size up and one size down from

my usual size.

The wire should closely hug the natural curve where your breast meets your chest wall. No poking

into the underarm, sitting on your breast tissue, or dropping below that crease. Underwires increase

in diameter by about 8mm per sizethats a really small difference but it could be a crucial one! If you

are having trouble finding your natural curve, you could use a washable marker to draw on your

crease and see how the wire fits into it. I know that sounds funny but some of us have probably

squeezed our breasts into too-small underwires and seeing that crease helps!

Ive made a page withlinks to wire charts,if you need them to compare wires.Elingeria ha

regular length : http://www.elingeria.de/downloads/Buegelsatz.pdf

Find your cup sizeFor those who want to leave out underwires, one way to find your starting cup size is by subtracting

the width of your high bust from your full bust.

I know this doesnt work for every shape and you need to be wearing a good fitting bra while

measuring.

Take your underwire size and compare it to your band size to find a cup size on this chart. My

underwire is a 32 wire, so I move over to find my band size and its corresponding cup, a 32B. (In

European sizing, a 75B.) My friends size is in green.

9/62

I know US/UK cup sizing gets a little whacky after D but hopefully the chart makes sense.

Some women with very large cup sizes may find that they need a larger cup to go with a smaller

wire.Smaller busted women may need a larger wire with a smaller cup. If you have a feeling this

might be your case, you can adjust the volume in your fitting


10/62

Pattern TracingLets take a look at our patterns!

.Ive been drafting different bras so I needed a quick and dirty way to test them without sewing in the

elastic. So Ill share how Ive been doing that. There are some things you cant predict in a tester bra

or cups, and you may just want to skip this part. But if you want to save your materials for the good

stuff and do some fitting and styling fun next week, give it a whirl!

Before I get to tracing, lets take a look at our pattern pieces. This is an illustrated scan of the pieces

in Elan 645, and most of your patterns will be in some combination of these pieces.


11/62

If you are working with a three-piece cup (such as the Danglez patterns), sometimes the lower cup

consists of two pieces, or there will be a side panel that reaches into the strap. A couple of the

suggested patterns also include a fabric strap piece.

Youll also notice that the band and cradle can have various seams, some with a seam below the

cup, some with a side seam, or both. These are mostly just style differences.

tracing the atternWhen tracing your pattern dont forget to transfer pattern markings like notches, direction of stretch

(the grainline) and bust point. Im going to trace a 32D from the Elan pattern.

The Elan pattern also has a little facing piece for the top of the cup. I might not use it but I traced it

anyway.

For my initial pattern, Im using this vellum paper to trace off but later Im going to transfer the pattern

to oak tag or something like card stock. I find it much easier and more accurate to weigh down the

patterns and trace around them with chalk, rather than pin and cut. You could do this straight away if

you wanted.

the !ea" a##$%ance!Now theres one more step I like to do and thats draw in the seamlines. Bras use small, precise

seam allowances. The major seams are all 1/4 (6mm), and trust me, these small allowances help

with sewing precision, especially in sewing convex to concave curves! They also help the curves to

lay smoothly.

The underarm seam on cups and top of the band are 3/8 (1cm), for 3/8 (1cm)picot elastic.


12/62

(Totally random prop with my little Czech car.) And for the Danglez cups:

The hemline and bottom of the entire band is 1/2-5/8 (12-15mm) for your band elastic. Check your pattern to see if it has specifics. For the Danglez pattern, add the width of the elastic you plan to use.


13/62

The center back and the strap seam near it do not have seam allowances.

Everything else is 1/4 (6mm). The center front of the band is either cut on fold or has a seam

allowancecheck your pattern to make sure! (ETA: I totally goofed and had 1/4 at 8mm beforeI still

dont think in metric!)


14/62

Bra-making Sew Along: A Trial Run

So these are my super purdy bra muslins. Or bra toiles, what have you!

If youd like to try a fitting bra, heres one way to approach it. I make a very quick bra using some

leftover bra materials and scrap. And no elastic. If this is your first bra, you can get some practice on

those curvy seams without the pressure!

Some suggestions for the cups: If you can spare some of your cup fabric for a test run, perfect! If not,

try using some woven scraps like cotton muslin or quilting cotton. But testing your cups in a stable

woven will obviously only work if youre making your bra from a stable fabric. If your chosen cup

fabric stretchesincluding stretch lace or any type of fabric with spandex/lycraand you dont plan onlining the entire cup, the fit will be different. The closer you can get to testing your cups in the same

or similar fabric to your actual bra materials, the better.


15/62

For my bras, I cut the cups from leftover Duoplex. I cut the cradle (or bridge) from muslin scrap, since

that needs to be stable. I cut the band from the lycra and powermesh I plan to use. Every band fabric

behaves differently and I often need to take in some fabrics depending on stretch. Ive unbasted the

bands and re-used them if they fit!

I wont get into construction details until we make our bras, but heres how I put it all together.

Sew the cups together. I added a seam to the center front of the bridge in case I need to adjust the

spacing.

Then sew the cradle to the band. Some patterns have a side seam, some dont. And now you get to

sew those cups into the cradle. This part is tricksy at first but dont be shy! Ill have some tips for youdown the road.


16/62

And this is the really fun part. To get this to fit, find a way to get the underwire on that cradle seam. It

will help pull the cup to the right position. You could baste in some of your channeling to the

cup/cradle seam allowance with a long stitch. This is what I do. It doesnt have to be perfect and you

can re-use the channeling later. (Cut it a little bit longer if you want to save it.) Alternatively, you couldtrysewing a tiny tunnelright on your seam allowance.

Baste in the hook and eye. I do this pretty loosely. To simulate straps I baste in ribbon or seam tape

in the back.

17/62

Band adjustmentsIn fitting your bra, try to pay attention to the fit of your underwire and band first and the cups second.

Many problems can be solved by getting the right frame.

A&'(!ting )an& #engthIf you band feels too loose or tight, its easy to adjust the length. It should fit well on the loosest or at

most 2nd hook. The hooks are there for you to adjust your band as the elastic starts to age. And it

willage!

1. Draw a line down the center of the band.

2. Cut the pattern along this line and spread or overlap by the amount you wish to take out.

(Remember this amount will be doubled in your bra.)

3. Trace and redraw the new band line making a smooth line connecting the pieces (red).


18/62

F$r a )an& that hi*e! (

If your band is hiking up, it may be too long so you can try the above adjustment. But sometimes

shortening the band isnt enough to keep it from hiking up. Perhaps your ribcage is narrower below

the bust so you need less length along the bottom hem. And every pattern has a different band

angleexperiment to find one that works with your body. This is also called a downward hikeadjustment.

1. If you have a side seam, line up the cradle and the band along the seamline. If your pattern

doesnt have a side seam, draw a line about 2/3 up from the CB to the cup seam.

2. Extend the center back line down by the amount you wish your band to go and place a mark

(blue). Extend the side seam line by 1/2 that amount and mark.


19/62

3. Slide down and rotate the back band to meet these new points. If you did not have a side seam,

youll have to slash the pattern along the dotted line. Retrace your new band line (in red, along the

seamlines). Dont forget to add back your seam allowances!

Gaing a#$ng the (n&erar"

This is almost the opposite of the above alteration. On my bras, I often had gaping running from the

underarm of the cup around the side seam, usually right where the channeling was topstitched down

to the band. I finally figured out that this had to do with excess length along the top of the band. The

band plays a role in giving some tension to the underwire, but since I had too much length, the

excess was crowding at the point of least resistance right inside the cup.

1. Measure out the amount needed to take out the gaping and draw in dart along the front of the

band at the seamlines (blue lines).

2. Cut the pattern along the blue lines and close the dart. 2. Re-trace the pattern and draw in a new

smooth line (red) connecting the pieces.

Note that if you have a lot of gaping at your underarm, you may need a cup adjustment. Gaping

problems wont be solved by pulling elastic tighter around the cup. I tested out this theory on several


20/62

bras: the ones in which I pulled elastic tighter actually resulted in more gaping. Pulling elastic tighter

while sewing ends up removing more of the elastic tension permanently so it stops behaving as it

should.

Bri&ge a&'(!t"ent!

This little space can take a lot of different shapes! If you find it feels a little tight or loose, but your

underwires and cups fit you correctly, try making some adjustments to the bridge. Tiny adjustments,

like 1/16 (1.5mm), can make a difference. Remember that whatever adjustment you make to half the

pattern will be doubled.

These are just a few alterations I have experience with but hopefully they give you some ideas!

Some great fitting questions have come up in the Flickr group. Thank you all, for being brave to

share what youre working on, and please be free help each other out because we all have different

experiences. Ive also posted some pictures of my tester bras so you can see the gory details. Ive

got a few adjustments to make myself!

Cup AdjustmentsSome tips for working with these alterations:

Mark in your seamlines on your pattern so that you can measure exactly how much you

want to adjust.

The best way to determine your alteration is by pinning out excess along the cross-cup

seams, neckline or arm edges of the cup to see if that helps things fit. If you need more

room you could cut a bit into areas of your tester bra to see what alleviates tightness.

Measure how much you needed removed or added and write it down. I keep the pins in

the bra so I can measure my little darts after I take it off.

O-era## -$#("e a&'(!t"ent

If you simply want to add or remove more overall volume in the cup, pinch out darts along the mainseams until the cup feels comfortable. Measure out this amount along the cross cup seamlines.

Spread or close the dart and redraw the seams.


22/62

Im just showing one adjustment right at the bust point but if you are adding or removing a lot of

volume, you may need to make several little darts or slashes along the seams so that you make an

even shape adjustment across the cup.

A&&ing $r Re"$-ing L$%er c( -$#("e

If you notice excess fabric pooling at the bottom of your cup, you may need to remove some of the

volume from the lower cup. Pull up the lower cup and see if you can pin some of it out. This

adjustment could also help lift the cups.


23/62

You will have to adjust the length of the uppercup seamline to match the new lower cup seamline.

The illustration above shows one way to do that, by cutting and overlapping to shorten the seam.

S"$$thing the ae.If the cups are just too (yes Ill say this!) pointy, you can always smooth out the apex curve of the

cup. When doing this adjustment, start small so you dont remove too much of the seam length. This

is pretty similar to doing the above adjustment. Maddie ofMadalynnehas agreat postexplaining cup

alterations, particularly this one!

A&&ing LitBoth of the above adjustments will add some lift to the bra in some way. If everything fits and you still

want a bit more lift, you can try flattening the seam of the upper cup. The flatter this seam is, the

more lift a bra has. (Balconette bras with 3-piece seaming often have a totally flat upper piece.)

24/62

To make this adjustment work, you will have to remove some length on the lower cup seam so that it

matches the new upper cup.

Gaing at the Si&e $ the c(

Pin out the excess along various points of the cup to determine where the excess is. Transfer this to

your pattern by slashing and closing the darts, as in the examples below.


25/62

A&&ing (n&erar" c$-erage

This is an alteration I did to my bra. It could help if you want some extra coverage or support along

the side of your cup, depending on your figure. This alteration requires both your cradle/band and the

cup pieces which run along your underarm.

Line up the cup pieces and cradle right along their seamlines.Draw in the new underarm line starting

from the band and going up toward the cup. In this illustration, Im also making my straps further

apart on the top of the cup.

A&&ing "$re c$-erage the t$ $ the c(

If you have more breast tissue at the top of your cup and want more coverage, you can always raise

the top seamline. Most of the patterns we are using arent entirely a full cup bra.

This new line can be either totally straight or just slightly curveda curved line will add a bit more

length.


26/62

Basic Style alteration

Ban& !t0#e

How about a longline? (Cool examples:Freya,Fortnight) I love these for style but theyve got a

function, too. The wider the band, the more supportive it is. And I think they look pretty sweet

underneath thinner tops. Ive made this alteration to a few of my bras:

You can lengthen the band straight from center front, side seam and back, as the lines in red

demonstrate. The longer these lines get, the narrower the band will at the bottom so if you need

more width you might have to try lengthening at a different angle (lines in blue).

Stra !t0#e

How about fabric or lace straps?

Again, style and functionthe less elastic the strap, the longer it lasts. This beautifulStella brauses a

scalloped lace and a silk satin strap in the front.

The back design is really up to you. I love having options in back strap designs. Its easy to change

your pattern back and forth from a u-back to a camisole back.

In a camisole style, the elastic works best if it is tacked down to both the top and bottom of the band.

You can do a lot of funky things with the bridge, too. If you are using longer underwires but want

create a little plunge effect, you can try using separator wires, as in this lovelyHuit bra.

These wires come in all sorts of shapes. The construction would be a fun puzzle, as you either need

channeling or a tunnel to insert the wire. I may try this on my next bra and Ill let ya know how it turns

out

De"i c(!If a demi style appeals to you, you can always take some of the height out of your cup and bridge.

This is an Elle Macpherson demi bra with similar seams as some of our patterns. To do this youll

need shorter or plunge wires, or clip your own.

29/62

I love playing the game of How Did They Do That? and often do a little investigation in the stores (it

must look funny, as I look inside the seamsthe things you do when you sew!). So I hope this gives

you some fun ideas as you continue your bra-making adventure.

Vertical Seam VariationI love a diagonally-seamed cup because it is especially pretty in lace, with an unbroken line of

scallops across the top. But its been fun to play around with seam directions for different style and

shape options.

In todays tutorial Ill share two pattern variations you can make to your cup:1.adding an additional

seam to your lower cup for a 3-piece pattern and2.changing the entire cup to a vertically-seamed

one.


30/62

A tip for these alterations:The main seams in a cup should cross over your bust point. In some

patterns, there is a notch at that pointusually right at the apexif not, find it on your bra and mark it

on your pattern so you know where it is. After your alterations, walk your pieces and double check

that the lengths of the actual seam lines match.

A&&ing a Sea" t$ the L$%er C(ONE: For a second seam in the lower cup, mark a line going from your bust point down to the bottom

seam line.

It doesnt matter where the line ends at the bottom so feel free to experiment! In this example, Im

dividing the lower cup into two relatively equal pieces, which will result in a seam that runs

perpendicular to the main seam.TWO: Cut the pattern piece along the lines and trace your two new pieces. Draw in a smooth, even

curve connecting the top and bottom seamlines. The curve should be fairly subtle.


31/62

THREE:Thats ityour new pieces! Dont forget to walk the seamlines and add 1/4 allowances to

the new seam.

1ertica# Sea" A#terati$n

For this alteration, first mark where you want your seam to start and end. A vertical seam doesnt

have to be straight up and downyou could slant inwards or outwards. I found my starting points by

marking these positions on a previous bra. It just so happens that my patternPin-up Girls Classic

has a notch right at the center bottom, which is usually where a straight vertical seam starts.

ONE: Mark the bust point of your pattern.


32/62

TWO: On both pieces, mark in lines on the top and bottom cups, going from the desired starting

point of your new seam to the bust point. I rotated the bottom cup in this example so I could draw a

straight line down the two.

THREE: Split these pieces apart on the lines. You should now have four pieces total.


33/62

FOUR: Line up the top and bottom pieces along the sides until the seamline along the sides of thecup form smooth curves.

The cross-cup seamlines will match each other for a short distance, but will not come together at the

bust point. Trace off the these new inner and outer pieces.

FIVE: Depending on your pattern style and where the apex is, one side may have smaller dart than

the other. In this case, the outer cup has the smaller dart, so draw your new seam line on this side

first. Draw in a smooth curve connecting the two upper and lower pieces close to the bust point.


34/62

On the inner cup, draw another curve of equal length. Because the dart on this side is so wide, the

curve will not go around the apex. (You need to take some out from that dart, if that makes sense!)

You can use a measuring tape to find the right curve length.

NB: The flatter these curves, the less length (and volume) the cup will have. In your fitting,

experiment with them to find the shape you like. If youd like to pull things in more, you canexperiment with making the inner curve slightly flatter than the outer curvea good tool to use in

shaping!

SIX: Smooth out all the new seam lines, mark your bust point notch, and add seam allowances.

In the above illustration Im also smoothing off that strap extension from my pattern, because Im not

going to use a fabric strap.There ya goa totally new cup!


35/62

Bra-making Sew Along: Cutting

Before I start cutting, I like to double-check a few things on my pattern:Check the cradle seam to make sure it has enough length for your chosen underwire. The cradle

seam should be the length of your underwire PLUS 5/8 (or 16 mm).

This extra length gives your wire about 8mm wiggle room on each end (called wire play in bra

drafting). If you have ever tried to sew a bra without that allowance, you might know the pain of

breaking a needle because you hit the wire while sewing down elastic (CHECK!) or your wires have

strained and popped the channeling seam (CHECK!). If you end up needing more length you can

add a bit more to one side or the other, or both. Dont forget youll have to add this new length to the

corresponding cup seams.

The distance between the cradle and elastic seam lines should be at least the width of your

band elastic (otherwise youll be sewing elastic into your cup!).


36/62

After that, it never hurts to walk your seams in your cups and cradle to make sure the actual stitching

lines matchespecially if youve been making alterations!

Lining $r interacingThere are many ways to stabilize a cup and remove some of the stretch. You can either sew a lining

underneath your main cup fabric, interface it, or both!

For my bra, Im cutting my entire cup and cradle out of lace and lining it with silk.

For stability, I interfaced the silk with afusible knit.You can see I blockfused my fabric before

cutting. Im a fan of blockfusing, especially when it comes to small pieces that get finicky and time-

consuming to interface.

For my friends bra, Im using simplex from a bra kit with lace on the top cup. Im new to this fabric

and debated over whether to fuse itits stable but has a lot of drape which I suspect will make the

cup drop a little. Shes definitely going to get another bra after this anyway!

The cradle or bridge area should not stretch at all horizontally. Again, I dont think a lining is

necessary for simplex but I went ahead and cut one out of sheer tricot.

Stretch &irecti$n!

All of your pieces should have a line which indications the stretch direction. Bra fabrics can have their

greatest stretch in either direction, so test your fabric to be sure! Even the more stable bra fabrics

have some mechanical stretch.

Regardless of the pattern, I usually cut my upper cups with the neckline running parallel to the

stretch. Unless Im stabilizing it, I dont really want this piece stretching up and down as it will stress

the strap, nor on the bias which tends to permanently stretch.


38/62

If you are using lace, 4-way stretch fabric or a print that you want to run in a particular direction, it

can be lined or interfaced to stabilize it.

Cutting#ace

There are many ways to use lace in a bra and I really love working out lace puzzles!

When cutting the lace, it is helpful to have your seam lines marked in your cup and cradle pattern. I

usually cut one side of the cup first to center the motifs. I make sure thestitching lineof the upper

cup is lined up with the lowest point of the scallops:

I also try to line up the piece so that the stitching line that meets the bridge hits a bottom point of a

scallop. When the bridge and cup are sewn together it will match up nicely:


39/62

I usually cut one side first, then flip over the cup pieces to cut another mirroring side. It just so

happened I have a 2nd pattern piece that I can flip:

But often when Im cutting a bra, I simply cut the first piece, flip it to find a matching side and

carefully run a rotary cutter around it.


40/62

Some galloon laces have mirroring motifs, some dont. If not, I try to get close so the motifs are

similar on both sides.

All cut!


41/62

C(tting n$te!

I like to transfer my master pattern to something like card stock or in this case oak tag (same paper

as manila file folders). Ive even scanned my pattern so I can print it out multiple times onto weightier

paper. (No more re-tracing!) This not only preserves the pattern but gives me an edge on which to

trace around with tailors chalk directly onto the fabric:

I use a small weight (or just my hands!), chalk around the pattern, then cut away the chalk lines. I like

doing it this way because it gives me a really accurate cut, while pinning sometimes distorts the

fabric (especially lycra and lace). This is just a cutting method that Ive picked up from pattern-

makersit takes me all of 5 minutes to cut a bra pattern!

Sewing the Cups

Before I break out the sewing machine, a couple of things that Ive been using on my bras.

A straight stitch foot. I use my foot as the seam guidethe distance between the needle and the edge

of this foot is exactly 1/4.

Of course, dont forget to switch toyour zig-zag footwhen sewing your elastic.I use astretch needle, size 11/75. This has been perfect for elastic and lycra, but also seems to

work best on all the tricot-type fabrics. For lace I sometimes go to avery small needle.

A!!e")#e the c(!

How you proceed on your cups depends on whether you are fully lining your cup, or just lining one

part (like the bottom)or not lining at all.


43/62

On my friends bra, Im using lace only on the top cup, as an overlay on the regular bra fabric (in this

case, simplex from a bra kit). I want the cross cup seam allowances to be totally hidden inside the

seam, so I stitched the three layers together with the lower cup sandwiched in between.

sandwich turned right side out, before

topstitching

On my bra, the outer cup is entirely lace and the lining is interfaced silk charmeuse, so I constructed

the two layers separately:


44/62

To flatten the seams, I turned the seam allowances over to one side and edgestitched onto the

allowances, just a tiny width away from the seam.

Your pattern may have instructions to press open seams and topstitch on both sides. Or

topstitch the seam allowances together to one side. This is really up to your preference and how

thick your material is! Most often, I like to edgestitch which flattens the seam enough for me.

So when I was first starting to make bras, I struggled with rippled seams across the cup. Oh the

dreaded rippled seam in knits! Since seam rippling is usually caused by one or the other layers

stretching too much, here are a few things to try:

If your machine has this ability, try lightening the foot pressure.

As you are sewing, try not to pull or stretch the fabric in any waylet your hands simply

be a guide.

Try sewing without pins! When sewing two different curves together, or concave and

convex curves, pinning pulls one layer into the direction of the other which can cause the

length to stretch. It takes some practice at first, easing off a pin here and there.

Eventually I went cold turkey pin-free! Which has improved my curves sewing and feel

for fabric handling.

Fini!h the t$ $ c(!At this point I want to finish the top of my cup! If you are sewing a continuous trim that finishes both

the cup and bridge, youll wait till youve sewn your cups into the band.

Both of my cups have two layers on topthe scalloped lace and non-stretch lining. To finish the edge

of the lining, I tried a technique based on one of my fave strapless bras. I sewed a strip of sheer tricot

along the outside top of the cup with a 1/4 seam allowance.


45/62

Then I turned, and top-stitched this down along the inside. I could have done this in reverse, too

which would totally hide the seam. Its pretty soft as it is. The tricot is cut along the least stretch so it

stabilizes things a bit.

To keep the lace from shifting around on top, I tacked it down in three spots with a small back-and-

forth zig zag stitch (almost like a bartack!). I saw this done in an Elle Macpherson bra and liked its

invisibility.


46/62

Since my bra has a vertical seam, I tacked down the lace to the lining with a couple of straight

stitches right at their joining seams.

After youve finished the top of your cup, you can baste the layers together around remaining edges,

so that the cup will be treated like one piece. I do this just inside the seam allowanceitll all get

hidden underneath channeling and elastic! When basting stretch lace, it sometimes wants to stretch

past the lining, as you can see in the above photo. Its just the nature of stretchI try to keep the

excess toward the bottom of the cup and just trim it off!

Other c( +ni!he!

There are loads of different ways to finish the top of your cup! Im always experimenting.


47/62

Left to right: foldover elastic as a binding, decollete orclear elastic along the bottom of scallops,

picot or piping elastic, lace and lining layers sewn right sides together for an invisible finish (which I

wrote abouthere).

Band & Cup Construction

Today Im going to assemble the band and insert the cups.

Since I am lining the cradle of both bras, I used the lining to finish the top of the bridge. With right

sides together, I stitched a 1/4 or 6mm seam across the top. I turned this right side out, pressed and

topstitched about 1/8 away from the top.

48/62

If you dont have a lining and interfaced this part, you can turn down the center top by 1/4 and

topstitch. Another idea: if youre using fusible interfacing instead of a lining, you could also sew the

fusing to the top of the bridge glue side up, turn and fuse for a totally hidden seam.

On my bra, I wanted the band seam to be hidden inside the lining so I sandwiched the band pieces

into the cradle and lining and stitched the side seam and top of the bridge at the same time.


49/62

Then I turned it all ride side out and basted the layers together so they can be treated as one piece.

On this one I sewed the band in separately

Now its time to sew in the cups. I think this is the trickiest bit by far. Everything else after this is a

breeze! But I promise, that with some practice, youll be kicking it out!

There are a lot of different techniques for sewing in cups. I like to sew both sides with the cup on top

and the cradle on the bottom andas I mentioned yesterdayI go at it without pins.

I start with the left cup. Remember how I cut with the scallops with the lowest point at the seam? I

line up that point right with the seamline on the bridge and start sewing.


50/62

The band is facing up and the right side of the cup is facing down. I sew all the way around the cup

to the underarm, lining up the notches.

You can also see in the above picture how I keep the two curves opposing each other right up to the

edge of the foot.


51/62

On the right cup, I start at the underarm.

When I get close to the top of the bridge, I slow down and release the presser foot a few times to

rearrange the layers, so that the scallops meet just at the end of the stitching line.


52/62

If youre having trouble with puckering, it helps to release the foot pressure every so often if the

layers start to bunch together. Speaking of which, its totally normal to end up with a few puckers now

and then. Just like sewing sleeve caps. I unpicked one bra like 5 timesugh That was actually my

impetus to go cold turkey on pins. Since then no more puckers and I stopped cursing my machine.

Bra Straps

Hey all, Im gonna take a little pause today before my final construction post. Im running a little

behind but I hope to be back tomorrow! In the meantime, a strap interlude

This might seem ridiculously simple but I could never figure out which end went where through the

slider. Maybe its because Im lefthandedthe visuals always look backwards. So this ones for the

lefties out there!

First I cut my straps. I like to cut each about 19 inches for insurance. The left side is going to be in

the back. The right side will connect to the front cup with a ring.

1. Threading the end through slider, with the wrong (often fuzzy) side of the strap facing up. I fold this

bit down and stitch a secure seam.

2. Looping the right end up and over and threading it through the slider


54/62

3. Pulling it all the way through to the left

The straps are sewn at the end but its always nice to have them pre-assembled. And Im glad I

checkedI forgot to take my own advice and buy extra strap elastic! The Bra-makers notions kit

includes less than 18 inches of it. So you can see in the top photo I changed my game. Thank

goodness I had a small bit of my silk left from which to make strapsand they had to be small. They

were made super easy thanks to Stephs very cleverrouleau tie tutorialat 3 Hours Past.My straps are assembled similarly to the nude ones, except the adjustment is going to be in the back

rather than the front

Elastic, Channeling and Finish!

Ban& E#a!ticIf youve made other lingerie goodies with picot elastic, youre probably familiar with how this is done.

The first side is sewn with the fuzzy side up and a regular zig-zag, getting very close to the picots.


56/62

If you want to cut your elastic to measure, a good general rule of thumb is to cut a length about 85%

of theseamlineof your hem. I like to feel it in as I am sewingjust something that happens from

experience with sewing elastic. How much tension I put on the elastic depends on the elastic quality.

I flip and on the reverse, stitch the elastic with a 3-step zig-zag. You could also stitch from the elastic

side. I prefer doing it fabric side up so I can keep the puckers away:

I set my 3-step at 4.8 width and 1.2 length. (I wrote all my bra stitch lengths on a little post-it note on

my machine so I dont have to look it up every time I make a bra or panties!) The 3-step is just

security to keep stitches from popping. But if your machine doesnt have a 3-step, you can use a

regular zig-zag and experiment with smaller stitch lengths.

Channe#ing

I know the channeling gets finicky. Readers have asked me about how I did this on previous bras so I

thought Id show in pictures!

I usually attach the channeling first, before putting in the band elastic. Its easier to make that first

pass without the elastic in the way but it adds another step and I wanted to make this simple visually.

First I lay down the channeling so its seam is right on top of the cup seam and start stitching right on

that seam. To make sure I dont accidentally stitch into the cup, I hold the channeling in my right

hand, lift it up, re-arrange it as I gowhile using my left hand to guide the cup seam. This has worked

really well for me.


57/62

I stitch all the way to the top of the front but stop and backtack about 1/2 before I get to the end of

the underarm seam. Its good to leave a little extra hanging off each end. This helps to finish the

channel neatly later on.

After stitching the channeling I grade the seams if there are a lot of layersand theres quite a few

here!


58/62

Before I do anything else, I close off the channeling in the front. Since the seams are still free and

not topstitched down, I grab the top of the channeling with the cup seam allowances and fold

everything else out of the way:

Then I stitch a really tight zigzag that almost looks like a bar-tack. Whatever it is, it needs to be

secure!

The closure is invisible from the outside. (On my friends braI forgot to snap a pic of my mine!)


59/62

Time for the topstitching! I switch back to my straight stitch foot (ok, I just found out my machine calls

this a patchwork foot). I turn the bra over and arrange the cup seams and channeling so they are

folded under toward the band. If youve ever done an understitch on a facing, this first part is just like

that. I hold the fabric on both sides a little bit taut, and start topstitching about 1/8 away from the

edge of the cup seam.

I have to keep feeling to make sure this stitch is going into the channeling. If you sewed your first

pass with the channeling seam on top of the cup seam, this shouldnt be a problem.


60/62

Then I do another line of topstitching with the first line of stitching lined up right under my foot edge.

This is about 6mm on my foot. Dont forget to stop your topstitching 1/2 away from the underarm so

you can fold it out of the way for your elastic.

Un&erar" E#a!tic

Nows the time to put in my underarm elastic. I do my first pass just like the band elastic with the

fuzzy side up. I use a bit less tension in this elastic than I did with the band.

When sewing in the elastic I have to fold away the channelingthats why I stopped stitching it 1/2

away:

Before folding over the underarm elastic I put in my underwires, sliding them in from the open

underarm sides toward the front.


61/62

At this point you need to decide whether you want your channeling to be closed on top of the elastic

or folded into it. Ive done both and it really depends on how thick the channeling is!Right below my thumb is where Im going to close the channeling with another bar-tack again:


62/62

I need enough room to fold down my elastic and stitch another 3-stepthis is where thatwire play I

talked aboutcomes in handy. I cant tell you how many times my underwire has reached right to the

fold of the elastica recipe for underwire and needle disaster!

After closing off the channel and stitching down the underarm elastic, this is what it looks from the

outside:

Almost there! Now I attach my straps and finish off with my hook and eye. Every pattern has a

different width at the end of the band for a hook & eye attachment. You usually need to adjust that tofit your particular hook and eye widthbeforeyou sew in your strap elastic:
