Sorry...if I don't have a picture already in my computer I don't know how to get it posted....will try to describe the one I have in mind.
3 or 4 (could be more) strips stitched together, cut into squares, then cut diagonally, arranged back into squares with the diagonal as the outer edge of the square and the long strips forming a pinwheel/windmill in the center of the block.
Will see if I can figure out this webcam and maybe I can get a picture!
