This is my friend Marty. His head was cold (Iowa winters can be brutal!), so he requested a hat.
Marty's hat is a simple crochet hat, made using wool yarn and a size N hook. My trick to making hats fit well is to use my own head as a form. Since Marty's head is much bigger than mine, I had to wear a ponytail while trying on his hat- and still make the hat even looser!
As you can see from the photos, Marty was really excited about the finished product. His head is now warm no matter where he goes!
