Making a bra - 2

Cutting and preparing undercup

Edited to add: I've made a pdf file for these instructions. You can find it here.
All pieces are cut with a 1 cm seam allowance, with the exception of the upper cup, that is cut to the scallop of the lace (see my earlier post on cutting lace).
Look carefully on the patternpieces how to layout the pieces on the lycra. Patterns have a line to lay them in stretch direction. Always check to which side the lycra has the most stretch.

Lower cup
The undercup is cut a bit larger then the paper pattern. This is because I use fusible interfacing for the lower cup. The ironing of this to the lycra could mean that the part shrinks a little, so I cut my lower cup after interfacing.
Needing a D-cup the interfacing is extra support that I find very comfortable. For a size A or B this is not necessary.

Apply interfacing

The lycra is on a piece of pattern paper, right side down. Then the interfacing laid on top, then again a layer of pattern paper.


Then iron the interfacing to the cup with your iron on the paper. This will prevent curling the interfacing and adhesive parts on your ironing board. While sewing lingerie, this is the only point I use an iron.

Finished cutting

These are all the parts of the bra, including the strenghtening tule for the center (behind the piece in lycra).

Assembling center and band

Sew the center piece in lycra with the right side to the tule, with a small straight stitch.

Lay it down like this picture, and stitch just below the original stitching on the tule (believe this is called understitching) This prevents the tule from turning to the right side.

Trim the seam allowance, turn and topstitch.

Stitch the tule to the center pieces with large stitches.
Not necessary to do this very accurately, later on it will all be trimmed. For now it will hold the pieces together.

Sew the band to the center piece

Open the seams and topstitch near the seamline. I use my blindstitch foot for this, which works very accurately (do this with almost all my topstitching btw).

Center en bands are now ready.

This was a very long post. Hope this is helpful. To be continued (my bra is already a bit further, and I already took pictures). But this is enough posting for one day.

  1. Do you topstitch on both sides of the center piece/band seam?

Comments are very much appreciated! I read all of them, try to answer the questions but don't always have time to react to comments.

How to sew a sleeveless top with facings

Edit to make this post only about the technique, not my ramblings on other subjects.
This is about making a sleeveless cowl neck top with a facing for both the front and the back. In this way no special finishing of the arm holes is needed. This method is based on Carolyn’s way of making a top with all seams enclosed.

Let me show you how to do this. It’s a good reminder for myself too, I forget when I haven’t done it in a while.
First you need a pattern that has a facing for the back that extends below the armhole. Also the front facing has to extend below the armhole. Easy enough to adapt a pattern, just trace a line about 5 cm (2 inches) below the armhole. The photo below shows you the facing of the back

Step 1: stabilize the back neckline of the back pattern piece

Step 2: with right sides together, sew the neckline of the back and the back facing, press but do not topstitch

Step 3: With right sides together, sew the armhole of the front to the armhole of the front facing.

Step 4:…

Dress Burda June 2018, construction picture

Once in a while a pattern shows up in a magazine that I want to make immediately. This Burda dress from the June issue is one of those.

It’s mainly the linedrawing that’s interesting, as the fabric they used for the magazine issue is not really showing the design lines. There would have been better accent options for the piping they uses.
If you’re like me and in general don’t look at the Burda instructions but do it by experience or your way anyhow, DON’T go on autopilot with this one.
Sleeveless dress: I close shoulder seams at the last possible moment. Not here, as you have to sew the bias band in between the center and side parts. The band has no seam (and I wouldn’t add one, too many layers of fabric), so the shoulder has to be sewn earlier than I’m used to.
Darts: I was inclined to sew all darts as first step and realised really just in time that the front dart is taking up the edge of the band. Front and back band! I was stupified why the angle of the band was not matching th…

Pants fitting, part 1

First, I'd like to thank all who commented on the fitting issues for my pants. I did look at Debbie's site and somehow thought it would not be the "one" answer to my problem, as I've become convinced that there is no one-step solution for me. But I think I have found part of the solution there. Tonight I spent adapting my pattern and making a muslin.

My starting point, after reading all the information was the Threads issue of January 2006, an article by Joyce Murphy Adjusting pants from waist to seat. In this article she describes "body space" as an important point in fitting pants. And it does make sense to me, as women have very different shapes. One needs more space in the front, and others (like me) more in the back.
The picture above shows the body space in my pattern, which is 15 cm. I tried to measure my own bodyspace by taking two rulers, and it is 19 cm, which means that 2 cm more is needed (half of the extra width in the pattern). The article d…
