Chemo Hat with HDC Brim

Earlier this month, when I posted my chemo hats over at 25 Things for Charity, there was some interest in the pattern I had used. Since I had modified several patterns to come up with those hats, I decided that I would write up what I had done and share it with everyone. I started with the "Basic Boy Beanie" in Stitch 'N Bitch: The Happy Hooker, and then I went from there.

I would ask that you use this pattern for personal or charity use only. If you do use it for personal use, please consider making one to donate to your local hospital as well. Also, this pattern has not been tested, so if you find any mistakes in it, please let me know and I will happily edit it.
