I have yarn in my stash that needs to get used up (call it spring cleaning). I started knitting hats to get rid of the extra bits of yarn. I'm not in love with them but they're soft and they'll do.
Susan Anderson's Itty-Bitty Hats book. I'm not crazy about the colors, but so be it, it's a stash hat. The important thing is that it fits him well and is soft and warm.
I didn't follow a pattern, I just started knitting, then seaming, then added the ear flaps and made the I-cord and tassels. My exact pattern is on ravelry, although there are better examples of thorpes and jester hats to follow.
