You might take a look at www.quiltville.com. She has some really great patterns. I'm particularly thinking of the one called "Bricks and Stepping Stones". Very scrappy, very easy, can be made any size, very easy instructions.
Just a tip: Depending on the pattern, and the size of pieces you need, it can be cheaper to buy a 1/4 year of fabric from the bolt, instead of a fat quarter. Check it out before you spend!
