I love these scrappy blocks. I made a quilt for my son like this and it was so much fun. I couldn't stop making the blocks. I would say "Just ome more and then I'll start dinner... Just one more and then I'll clean up...Just one more and then I'll go to bed!!" Well, you get the idea. It was so much fun because each block was different. I always used a fun picture fabric (like animals, or soccer balls...) for the center and then all different width strips around it. I want to start another one soon.
If you frequent thrift shops and garage sales, you can often find a bolt of inexpensive cotton to use for backing, too. Or sheets will also work nicely. This is a great way to use up scraps!
