Two piece sleeve – drafting comparison

In general I’m very impressed with the pattern drafting classes by Suzy Furrer, as you have read in previous posts. Watching her doing the two piece sleeve though I had my doubts. It looked so different from what I’m used to in a two piece sleeve, both from commercial patterns as from the way I’ve drafted those before.

After my holiday I want to make a jacket, so I started changing the sloper to a jacket sloper and thought it was time for a sleeve draft experiment. I drafted the two piece sleeve using Suzy Furrer’s instructions and drafted it too using the method I was already familiar with. For both I used the same draft for the jacket itself.

Writing this post as much for those interested in drafting as for keeping track of what I’m doing myself.

The first picture is the way Suzy Furrer starts her two piece sleeve, her base is the normal sleeve draft and you take the outside parts and combine those to the under sleeve. The second picture is the Danckaerts method I’ve learned in the past year or so. In this system you don’t start with the base of another sleeve, the instructions are especially for drafting a two piece sleeve, based on the circumference of the armhole.

What I noticed in Suzy Furrer’s method is that there is less curve to the sleeve. She instructs you how to make it curve more forward, but in the result it’s less than in the other method. Also, because the “square” used in her method was rather wide for my armhole circumference, the result is an upper sleeve that’s very wide at the bottom, and an under sleeve that’s very narrow.

There is one important difference between the drafting systems: in Suzy Furrer’s method you decide yourself how much ease you want in the sleeve cap, as you measure the front and back length including the ease while drafting. The Danckaerts method is designed to always have 4 cm of ease. In the instructions it says: the sleeve cap must always have 4 cm of ease. Opinions differ on the need of ease at all and to how much is needed depending on the fabric you use. To me 4 cm is too much in general, I prefer less, so it will be a bit more complicated to change that in the pattern.

To me the draft of the under sleeve looks too narrow in Suzy Furrer’s method. To really compare I will make up a muslin of the jacket sloper and use both drafts.

  1. Hi Sigrid, this is really interesting. I agree that the two piece drafts I've seen usually look like the second method. It will be interesting to see how these make up. Thank you for your posts about Suzy's classes and book and gor answering my question about buying the book, in so much detail. I've just taken the plunge and ordered it. Even to .new Zealand pistage was only 24USD which compared to fabric shipping is actually very reasonable. Am following your drafting oosts with great interest!

  3. I am looking forward to seeing your sleeve muslin. The narrow under sleeve looks very odd to me!

  4. Thank you for writing this post and taking so much time to take pictures so we can look over your shoulder.

    I just tried drafting my first (one piece) sleeve but haven't sewn it up yet. I'm looking forward to your next post and seeing how the muslins turn out.

  5. That's really interesting. I've never seen a two-piece sleeve that looked like that, either. I'll be really curious as to how your muslin works out.

  6. This is fascinating and I thank you for doing this comparison. It's quite illuminating. I also think the the crazy undersleeve is quite odd looking. But if it works? Can't wait to see if it does. Have you seen the sleeve Robin did from Furrer's draft? It was perfection. One of these will work perfectly for you, I'm sure.

  7. Very interesting! Looking forward to hearing how they sew up.

  8. Wat een bijzondere vergelijking. Ik ben benieuwd naar de exemplaren in katoen en het verschil aldaar. Leuke zoektocht zo en fijn dat ons erin mee wilt nemen.

    Groet Neeltje

  9. Thanks for sharing this info Sigrid; I find it very interesting and I'm also curious to see the comparison between the two finished sleeves on a jacket.

  10. I look forward to seeing both version in muslin, if you decide to make them up for comparison.
    My next project now is a jacket with a 3/4 length sleeve. I bet that makes a difference too (as opposed to a full length sleeve).
    I haven't sewn nearly as many jackets as you have, and I found that watching the class on lapels and notched collar to be extremely helpful in getting my head oriented to the project.
    I'll be sewing up a mockup with all the facings and everything so I can get a good fee for the sewing construction.
    Thanks for sharing this! There is always more to learn!!

  11. I took Suzy's sleeve class and while I haven't drafted with her, it looked strange to me. I drafted sleeves with Kenneth King and the sleeve looked more conventional than Furer's

  12. Hi Sigrid. I was just reading this post about Suzy's odd-looking two-piece sleeve. I have all her classes and have drafted my slopers so am rather interested in your comparison and in anything related to pattern drafting. I then did a Google search regarding the other Danckaerts drafting method you mention. Interestingly enough, I stumbled on a Threads magazine article (#182 Dec 2015/Jan 2016) which discusses converting a one-piece sleeve into a two-piece one. The under sleeve looks like the one under Suzy's method (pointy at the bottom) UNTIL they adjust the hem portion. Once finished, to me the sleeve looks a lot like the one you drafted under the Danckaerts method.

    Here's a link to the article: http://www.threadsmagazine.com/item/45190/how-to-draft-a-two-piece-jacket-sleeve-from-a-one-piece-pattern/page/all

    Thanks for all your posts. I read them with interest.

    1. Hello Joanne, thank you for the link. Very interesting and looks indeed more like rhe Danckaerts method.

  13. Well, as far as I can see for the Suzie method, the problem is that you started with a sleeve sloper that has no elbow dart. If you start with a darted sloper, it would have looked a lot like the Danckaerts system. That's how I do it, at least--with the darted sloper.

    1. Thank you for your thoughts. You could be right and I would have to look into it again. Will do that at some point

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 th…

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).
