How about something like this? It's from the Fat Quarterly Shape Workshop for Quilters book. If you make it smaller, it would be great for a kids quilt, and with the bigger centers to the blocks you could actually see the rocket ships on the fabric (where the bird print is in this picture).

I love this pattern - I am planning to make it with the Oh, Deer! line from Momo
