Gym pants muslin

Though I would like to sew the top or jacket, I’ll have to start with the pants of the active wear set I want to make. Not the most interesting part, but the pants take up most of the (black) fabric and I can’t cut the top or jacket before the pants are cut. The remains of the black fabric will determine what I can use for jacket and top(s).

In the same issue of Knip Mode as the top, there is also a gym pants pattern. I made a muslin of the top and it was fine (will make a picture later). I used the size that I needed by the size chart for the top and did the same for the pants (2 sizes larger). For the pants I thought that it looked large. So I compared it with a pair of rtw gym pants I have. This is a very good pair, and relatively new, but there is a large hole in the bottom part of one of the legs. Still wondering how that came to happen.

Look at the difference! And the rtw pants isn’t even very close fitting.

Back to Pattern review to search for other (magazine) options hoping that something would show up from a magazine I have (this is the way I found the Knip mode top pattern, Melissa had a review of that one, so no coincidence Melissa!). Burda 11-2007 showed up with a few reviews for a pair of yoga pants. I traced those within the Knip Mode pattern, I marked the lines, quite a difference. Time for a muslin, as the other rtw pants I have, are smaller and have a closer fit.


A quick muslin showed me that:

- it was too wide, I took in 2 cm on the side seams and 1 on the inseam. That’s 6 cm in total!

- the front had a strange pleat, I compared it to my rtw pair and changed the curve , much better

- a little extra height is needed in the back


I’m not going to show these on me ;), the fabric was bought many years ago for DD, at 17 this fabric no longer has any appeal to her (or me).

In the end I think I could have used the pattern 2 sizes smaller. Next is sewing these in the good fabric.


  1. Yikes that fabric is deadly.

  2. Your dd must have been really young to have liked that fabric! Sewing exercise clothing seems to be a trend these days.

  3. Um, wow, those are some major differences from the RTW garment. Good use for that fabric that is not favored any more!

  4. You're making a muslin for gym pants :-)?!? Don't you make them in stretchy knits? And how exactly do you get muslin fabric with precisely the same degree of stretch, not to mention thickness?
    How about just cutting them out with an inch side seam allowance, and adjusting on the fly?

  5. That is a perfect (muslin) fabric! Such a special piece it feels good to liberate from the stash, and one can cut into it without a trace of indecision. :) I had to sort through 3 fabrics to find my 'wearable muslin' today.

  6. Nice blog! the content which is mention in this blog is really understandable and informative. I really like this blog and thanks for sharing.

  7. I never tried this material on in pants. I do have a muslin sports bra, it is not for working out though but feels super comfortable wearing them to anywhere and everywhere. I would like to try these pants also who knows it might just fit me perfectly.

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…
