I tried drafting that block on graph paper. I got it to "work" on a l6 x 16 grid and on a 10 x 10 grid. Either way, the center square can be dealt with using the partial seam technique. I do not know how to get images from a Motorola phone onto the quilting board.
If the author made 15 inch finished blocks, I think she used a 10 x 10 grid with the blocks set on point.
