I'm working on a seamless yoke sweater from KWT. I still have a bunch more rows until I really need to worry about the hem, but I thought I'd ask now. I'm using Kraemer's Tatamy Tweed. It's 45% cotton & 55% acrylic. Obviously, the hem in its current state is rolling. She describes how to add a hem (pgs. 34-36), but has anyone done it? Does it pull in enough to stop the rolling? Will the cotton blend make a difference with the hem's end result? I'm trusting in her plan, but I'd like a little reassurance from you guys.
