I just bought a book on Scrap Therapy and it sugests 5", 3 1/2", and 2" squares. Has some very pretty patterns in it using these sizes. Been working on that. Little teeny peices I put in a plastic bag and save for stuffing toys etc. I have just cut a big square denim pillow for my cats and I'm using these scraps to fill it. Waste not want not as they say!
