The yarn is Rowan's Cocoon! It is 80% Merino Wool/20% Kid Mohair. It knits up quick coming in at 3.5 sts/inch on a US 11. I just finished this ribbed watch cap on a US 10.5. I love the stitch definition, the feel of the yarn and the warmth! I'm thinking about picking up sts to knit an attached cabled scarf. We will see where that idea goes!
