Ziggi jacket – changes to the pattern

Thank you for your comments on my running.It seems that sewing and running is a combination of activities regularly done. I do plan to make workout gear (e.g. Melissa’s legging pattern is in my to sew list), getting the right fabric is a bit of a problem. I might try to use some swimsuit fabric that’s laying around for a first try of the pattern.

Back to the Ziggi jacket. I hope to finish it tomorrow. Here’s a sneak peak again. I did say in a previous post that it might take me as long as a Chanel style jacket. I didn’t count the hours, but this certainly is a time consuming project.Mostly due to my choices of fabric (all seams have to be catch-stitched to lay flat) and finishing (piping added). Well worth it.

Before I show the changes to the pattern let me say that these changes are for my figure, they are not a mistake in the pattern. I prefered to have more waist definition too.
Combined with the full bust and narrow back figure I have , I made the following changes. Click on the pictures if you want to see them larger.

At the bottom (left side of picture) I came back to the original seam line (pattern is with 3/8 seam allowances), but otherwise took quite a bit of width out of the back, including at the top of the pattern pieces, that are sewn to the yoke.

At the front I took out a bit at the waist too. When sewing I straightened the line a because I realized I had to sew in the pockets/zipper and too strong a curve was not good there. The center front part was not changed.

The yoke was a bit more work. It had to stay the same length in the front, the shoulders and back had to be shorter. In the next picture you see the original pattern to the left and mirrored my new pattern piece. Most obvious is that the armhole part of the yoke (in the center) is more curved in the changed pattern piece.The length is the same.

This is how I changed it.
I drew lines from the shoulder notch to the neckline and a line from front to back seam.

The vertical line was cut from the back till the front seam, and from the edge to the front seam, leaving a little “turning” point. Of course it separated a little after this picture. It’s just important that the seam line is the point you’re working with, not the edge of the seam allowance.

Then the pieces are shifted like this, the front line is not straight any more, but still the same length. The back seam is overlapping, as are the lines at the shoulder. A little bit extra space is added, but I considered that too small to bother about and it was ok.

All pieces taped together again and the seams trued (straightened in this case). The shoulder seam was 11 centimeters and is now 10 centimeters. The back seam of the yoke was 14.5 centimeters and is now 13 centimeters.

If you want to you now adjust the seam allowances too,

Also check the changes to the back pattern pieces. The seams on these parts must together be the same length as the seam of the yoke. The other seams of the yokes are not changed in length.


  1. It is very interesting to see the changes you make to the paper pieces.
    I hope that you manage to do some sewing this week end. I am completely surrendering to the lovely weather and gardening!

    I also checked the link to the NHS program, I should maybe give it a try, see if my knees can cope with running. I used to run 6 kms 3 times a week. With a weather like today, it is a perfect excuse!

  2. Very interesting! I have "narrow back syndrome" as well and now have one more way of handling it. Thanks, Sigrid!

  3. I cannot wait to see the completed jacket. The color and piping are just divine. Thank you for sharing your pattern alterations also. This gives me some ideas on how to address some of my fitting issues.

  4. The jacket is looking so good - I am the opposite - broad back lol.

  5. Thank you for mentioning that these are YOUR changes, to accommodate your figure first and your style preferences second. I do these changes to patterns all the time, and feel guilty that I am untrue to the designer's vision, but I am the one who has to wear the garment after all.

    This is looking quite good.

  6. The jacket looks very good so far, curious how it will look on you. The changes you made on the pattern are very interesting, thxs. I'm learning here..

  7. Fitting is such an interesting topic and an ongoing challenge. Your jacket is looking fabulous.

  8. Thank you for showing all the details on how you altered this. The jacket is looking so gorgeous!!!

How to sew a sleeveless top with facings

How lovely to read the nice comments on my jacket. Grumpy without coffee commented that the original artist for the cartoon (which apparently was for books) was Sarah Andersen. Thank you for mentioning it. Beckster asked about the way I closed the center back seam of the lining. I did it by machine. She also said “Although I have not tried it, I have been told that the lining can be made by using the pattern minus the seam allowance and facings.” Well, certainly not without seam allowances, it should be without hem and without the facings. Important is that you have about 5 cm hem in the jacket for this to work. And I would always make a center back pleat. It gives you space to move without the lining pulling on the fabric. Next time I make a jacket I will try to make photos of the process of bagging the lining (Patsijean said she would have liked to see them and probably more would be interested). Might take a while though, see the end of this post.-----------------------------I mad…

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 the si…

Hilarious description

This week I bought the January Burda issue and browsing through it this top, and especially its description had my attention. Written by someone who has no understanding of modern, functional fabrics and never goes to the gym. Don’t know whether it’s the same in the English issue of the magazine, but in Dutch it says “Sport shirts often have the disadvantage to be close fitted.  This restricts your movement. Our suggestion: make this shirt with a full draped back.“I didn’t care to check their description of sports shirts they published before, but thought this one was hilarious.Off to trace a pattern from this magazine (not this one).
