Bethany Reynolds wrote several pattern books using the stack n whack method. She may even have originated the method. You should be able to find one (IMHO you need to start with the first one cause the patterns get more complex in the second book) in your LQS, library or ebay. If you select a fabric of the type she recommends (large multicolored print on solid background) and follow the instructions, you get fabulous blocks. I made a lovely wedding quilt using her first book.
It's probably the most fun I have had as a quilter because every block is different and you just marvel that they came out of the same fabric.
