Knitted CD Cases

My pal Sarah is a musician, and when she sells CDs at her shows, she likes them to be a little unique. That's where I come in. Not long ago, we had a little knitting party to knit up some cases for her CDs. I started and tore out about 25 cases, but this is the final product. Of course I forgot to write down the pattern I finally stuck with, so I can't reproduce it, but generally I knitted two diamonds and sewed them together about 3/4 of the way around. Don't ask why I didn't just sew two squares. It's a mystery.
