Using the Swirl method, mentioned by a number of posters, works so well. It makes you heart beat the first time you remove a couple of stitches, but the results is simply amazing, flat an you will have the colors going as directed. It may take a couple of blocks to get this technique to feel natural, but it Does work. I made a double sized quilt that was all pinwheels, I had lots of swirling and a beautifully flat, no lump quilt.
