My sister talked about a coworker who knits these, and I said I could make her one. I just started the hat around a hair rubber band and added a flower. There are endless possibilities -- including the vertical stripe hat that starts as a tube and is finished with single crochet at the top. This was just the quickest way to get it done since she was just visiting for a couple days. Now she'll have warm ears when she's doing carpool duty at school.
