I have two that I like and have made (and want to make again). One is called "diamond delight" and is found in the book Charmed, I'm Sure by Lesley Chaisson. The other one is in the book Nickel Quilts and Borders (can't put my hands on it right now) and looks like a hopscotch board. I did both of these scrappy, so they may not be what you are looking for.
