Missouri Star's Double Slice Layer Cake is a quick one that is free. It is sort of like a Yellow Brick Road, and you can do it with just a few fabrics instead of a Layer Cake also.

Let me see if I can find any that I have made, and I have made quite a few.
(When I like something, I like it!!) Okay, the first is about 6 fabrics and the second is from a Layer Cake. Maybe this pattern could work for you?
