I am active with our local Project Linus chapter. We have used a lot of the AZ Blankets for Kids (
http://azblankets4kids.com/) patterns when making up our kits. The colors and fabrics must be "kid-friendly" and made according to the organization guidelines. There is some flexibility in the sizes according to the needs of the facilities where the blankets are donated through the chapter. We have found there is a real need for larger throws for the teenagers, and there is always a need for blankets for boys. Why is it always more fun to make them for girls, do you think?
The local animal shelters need blankies for the puppies and kitties, but they can be made with fabrics that are not kid friendly. One of our PL blanketeers also makes blankets for the Humane League from all sorts of other fabrics besides 100% cotton. She always rounds up scraps of fabric and batting at our PL Q-Bees to use for the shelter.
God bless you for your interest in touching lives.
