I have a much loved Cabbage Patch doll that I used as my muse and created 5 drafts before reaching a final pattern that, in my opinion, is perfecto!
Shirred around the legs and the waist these doll’s knickers are designed to fit around an 18″ doll/teddy. However, I found that anywhere from 16″ – 20″ was ok. I designed my pattern to accommodate an actual bum on the doll/teddy concerned and shaped the leg/crotch intercept so that it sits nicely with no bunching. I used all types of knit and some worked well, others not so well so it really is trial and error with how well each type of knit will shirr. As a general rule, the thicker the knit the less it will ‘shrink’ when shirred. Ideally you want it to ‘shrink’ a lot as this is what allows the knickers to fit a wider range of doll/teddy sizes. And yes, those are raw edges. The good news? Knit doesn’t fray so no need to finish the edges – raw is all good.
