Thanks for all the lovely comments everyone! To answer a few questions - I used an old book that my mom got me in the 80's, its called Bucilla Knitting Primer. It has 100 different stitch patterns and instructions for how to make a blanket with the squares. I'm almost certain that you can't get this book anymore, but I'm sure some of the newer books out there would have something similar. Each square is knitted, then a row of single crochet is added around each square to make them a bit more uniform (each pattern has a different amount of stitches) and make it easier to put them together. I then attached the squares together with a row of single crochet. To finish it, I added 4 rows of single crochet, one in each color. I debated about sewing a backing fabric on it, but I don't htink its necessary, and the baby its intended for is due in April and won't need the extra warmth!
