This is a traditional granny square that I've seen several places. I've used it for a blanket and a bag. When someone asked me for the pattern, I searched the Internet, but I couldn't find it. So I wrote it down, and now share it with you too!

Scrap yarn
Suitable crochet hook

Depending on the yarn.
Worsted weight yarn - appr. 12 cm (4 3/4 inches)

This pattern was designed for an afghan to be donated to Project Linus, a charity that donates blankets to kids in hospitals. Project Linus requires that all blankets must be made using acrylic, but the pattern could be used for any yarn. The design was inspired by the granny square and the fact that Arizona is a warm climate. The open, airy feel of the stitch allows the blanket to be cuddly without being bulky.
