The videos below walk you through the entire 'granny square beret/cap' pattern found on headhuggers.org. I have written permission from Sue of HeadHuggers.org to do this tutorial.
HeadHuggers.org is a charitable program that brings crafters of all kinds together to create hats and get them into the hands of people going through chemotherapy, which causes the individual's hair to come out. The belief of HeadHuggers.org is that the person has enough to worry about with worrying about their head being cold.
In order to follow along with these videos, you will need to use the written pattern located here (will open in a new window):
Hopefully this pattern will help those struggling with the pattern get through it and have a wonderful hat suitable to give away to someone who can use it.
