You do not have to be a Harry Potter fan to love this hat. This is probably one of my favorite hats in the box of hats going to Kenya. The band of the hat is different than most, which is part of the appeal of this hat. The pattern includes different bands if you would like to change things up a bit.
This free pattern was found here. I used size 8 needles and some more of my Jo-Ann Rainbow Classic in Lavender Pink Multi. Since my yarn was pretty bulky and my needles were smaller than recommended, I opted to make the largest size hat. The hat is a little small for an adult and would likely fit an 8 year old, if I had to guess. But I love it. And since the orphanage in Kenya needs all different sizes, that was not a problem.
