I'm getting an early start on winter. Found a bag of stash in the closet, and I'm now working on a pair of blue wool ankle warmers. I think I've still got a bag of ankle warmers in the car, so if you encounter me at the postoffice or farmer's market, and you're feeling a spring chill, I can take care of you.
Most of my ankle warmers are made of synthetic threads, acrylics, but a few pairs are knit with wool yarn. Wool demands special care in washing, so if you'd rather not bother, stick with a synthetic thread. Some folks are allergic to wool, but if you are, you probably already know it.
