I got the pattern from Chris Simon's Page.
I am hoping to make one more to send to them too. It was a lot of fun. I really enjoyed doing this square.
I am going to make an afghan to commemorate my losing weight too. I think I am going to make one 12" square for every 10 lbs. I lose. I want to make a sampler, so it will give me a chance to try out lots of neat patterns. :-)
