Pink Poofball Hat

Just a very simple pullover pom-pom hat I made for the winter. Made in half double crochet instead of my regular single crochet. I already forget the brand of yarn I used, but it was a thick, soft yarn, and I just had to buy it and make something from it. I don't know why I picked pink, which isn't really my color, I was just in a pink mood I guess. Anyway, it's very soft and warm.
