"I like to keep my knees warm, but don’t want to wear long underwear all year round. Regular legwarmers tend to feel too tight for me and also, a bit itchy. So I cut the toes off some very fuzzy chenille socks and use them over my calves or knees, and under my jeans. A more organized person might stitch around the cut edge, but actually, it’s fine without hemming".
These leg warmers cost about five dollars.
