I WAS going to make this for Christmas, but since I needed to make sure it fit, and they saw me working on it, I went ahead and gave it to Elijah already. It's a Finn Hat from Adventure Time.
I used this free crochet pattern, and adapted it to suit my needs!
And so you can see what I was attempting to do, here is a picture of Finn. The hardest part are the ears/horns/whatever the heck they are. Location and size. I probably should have went a little larger on the size, but it's too late now.
