Here is a headband I made for my MIL Betty. She requested something absorbent that she can wear under her riding helmet (she rides horses). This is done in a seed stitch (cast on 16), size 5 needles, with a cotton/elastic blend yarn, 20 inches in length. The yarn is Fixation by Cascade Yarns, color # 5104, 98.3% cotton, 1.7% elastic. Hmmm... I'm thinking it looks like terry cloth and it feels like it too!
