How to… slim a sweater
I’m not scared to alter sweaters anymore, having practiced a bunch now, and I’m not even using a serger.
Here’s how to do a sleeveless shell I just refashioned from a giant silk sweater set:
Try the thing on. Measure how much needs to come in on both sides. Pin it up.
Line up the underarms and the bottom edge when pinning, ok? Stitch, using a good zig zag.
Trim close to the seam. I like to stitch the same way again finish the edges.
For the outer cardigan, or any sweater with sleeves, you do the sides first, then the sleeves. The amount you trim off the sleeves will likely taper as you get closer to the wrist.
