I've made several different patterns using the crazy cutting and switching method...all thumbs mentioned it quickly above...after making your cuts, take one piece off stack number one and put it on the bottom of that stack, then take two off of stack two, three off of three, etc. When you then sew together all the pieces on the top of each stack, you have a block with all different fabrics, the next block, made from the second layer of all stacks, will have a completely different layout, etc. and in the end, no block will have the same color layout.
