Sock yarn, by the way, is basically just a 4-ply fingering weight yarn. I've learned that superwash merino is the best plan if you are making socks for a gift or intend to wear yours as a daily accessory. This yarn doesn't pill up like plain merino, it doesn't have to be hand washed or line dried, it doesn't shrink, and it's nice and stretchy. And it's super soft!
Here are a few of the yarns on sale:
