Thank you! I used a metallic gold trim from Joann, so it's kind of rigid, which I think helps it stay up. I cut out four pieces: one that wraps around the top and was sewn shut, two pieces that were wrapped around my leg and were sewn to the top and bottom pieces, and the bottom piece, which velcros shut. It stays up on its own, but I bought some sock glue just in case, so you could also try that!
