I made a few different colored chemo caps for a friend from high school a few years ago. I made them from the thin fleece from Walmart. She and I had fun designing them. He favorite one was the one we styled as curly pigtails. It was just a round hat pattern and added the “curlies” on either side. (She always had beautiful, smooth long blonde hair, so she really liked having long bright red ringlets hanging on her shoulders.) Lol.
