I had my birthday last week, and since the weather's thankfully getting cold enough for hats, I thought I'd make this as a birthday present to myself
The pattern I used is this one. I did the teen/adult size, which ended up being a little big for me (or maybe I just like my hats a little snug, I don't know). I also made a few modifications to the pattern. I'm really pleased with how it came out! I always wanted a hat with earflaps!
A bit more info on this project can be found on my blog.
