Yes, I know it's summer and the last thing you probably want to do it put wool on your head, BUT...
Introducing Ulee's Hat, a simple Fair Isle hat ideal for Fair Isle beginners inspired by the film, Ulee's Gold. I've always love yellow and gray (or "grellow" as my friend calls it) together. Add a dash of corrugated ribbing and a lovely striped decreased crown and you have a wonderful hat!
Knit in The Fiberists squishy and amazing Curie Heavy Worsted, you'll need 2 hanks (one of each color). You can easily get 2 hats out of 2 hanks, so why not knit an inverted version for a friend?
