I'm lovin' this Tofutsies sock yarn. (Click on the photo to see it a little better. Not perfect but better.) I'm using a free pattern from South West Trading Company. Look for the pattern under Free Patterns. The yarn does have a tendency to split but since I need to keep an eye on what I'm doing with the stitch pattern it's not a big problem.
I really like this color way and the fabric makes me think of haberdasheries. It's hard to see the lace pattern until it's stretched. The fabric has a slightly dry feel to it, more like cotton than wool. I can't detect any shrimp or crab shell, nor does my cat.
