So I am going to knit some socks for a Christmas gift. I haven't knit many pairs of socks, especially lately. I don't have much experience with sock yarns, though I've used Trekking and liked it a lot. So I ask, what's your favorite sock yarn? Why? Pretty please leave me a comment and tell me. I'd like them to be soft, hopefully washable, warm, and - you know - yummy!
