Oh, right, and socks! My favorite pattern for cotton socks is the Sodera sock pattern. It has a lot of yarn overs and knit through back of loops which seem to make it work. I used "On Your Toes Bamboo" for those.

My leafy lacy socks use plain old Knit Picks cotton and seem to work fine. They're short, so they can't slide down very far.
