64 Squares will eventually be an afghan

These are the 64 squares needed to make my nephews afghan. I don't think I will have them put together by his 16th Birthday in mid September. I will have them done by Christmas though, just need to figure out how I am going to put them together. I have to get out some afhgan patterns and how to books to figure out if I want to crochet them together or mattress stitch them together.
