This block has infinite possibilities. It scales easily and that big center square can be replaced by 4-patch, pinwheel, square in a square or just changed to a coordinating fabric. For more variation think half-square triangles in the corners.
Marcia Hohn has a page of 12 inch blocks on the Quilter's Cache site which are all variations on the sawtooth star. Christine is using it as the basis for a Christmas Block Swap on the Quilting Forum on about.com. I am making three sets of blocks.
Even though I thought I was done swapping for the year, I couldn't resist.
