This will be my next project using Shokay 100% yak yarn. Get the free pattern from http://www.shokay.com/. This yarn is so yummy. Softer than cashmere, if you can believe it! And it's machine washable. It actually gets softer the more you wear/wash it. I'll be doing my hat in solid Azure with a Buttercup trim. I'll keep you posted. It's time to start knitting!
