The following question was sent in by Gayle F.
Q: How do you customize a sweater when your upper arms are a completely different size from the rest of you? For instance, my upper arms are a size 18, my torso is a size 12. It makes knitting sweaters hard.
Continuing from my last column, which covered drop shoulders and circular yokes, this time we take a deep dive into set-in sleeves. A third part, about raglans, is coming.
To understand how to modify a set-in sleeve, you need to understand the relationship between the pieces that connect to create one: the armhole and the sleeve cap.
The armhole and sleeve cap are engineered to fit together comfortably around your shoulder joint. The perimeter of the armhole (measured once front and back of the garment have been joined) and the edge of the sleeve cap must be the same length for the pieces to fit together perfectly.
