I'm planning my first handspun/handwoven project -- a scarf. And it's for an assignment from my weaving guild, a result of playing the weaving game. I want to use a warp that contains wool yarn (sheep breed unknown) and another yarn that's 70% shetland/20% alpaca/10% sillk. Am I asking for trouble doing that? I thought that since wool is the primary fiber that there shouldn't be too much differential shrinkage.
What do you think?
