We've been spinning this up. It's a Sheep2Shoe kit from BMFA. This is what the sock yarn really looks like. The first three photos are of the same skein. I tryed Navajo plying it. It was so tightly twisted that I thought it was ruined. Once we got it into a bath and hanging with weights, it looks pretty good!
These two sets I plyed regularly. I think all three came out pretty close to the same weight, maybe a heavy worsted.
