After reading the post on Soulemama's blog. I headed over to Mama to Mama for the info and the pattern for these knit hats. The kids rummaged through their drawers to find t-shirts that were getting too small (we left out the ones with skulls on them) and we set to work. In no time we had 13 caps to send off. These were super easy and are going to a really great cause - please check it out if you have time.
The only problem is that we ran out of shirts. I think we're going to hit up some of our friends and neighbors.
