I don't know the name of the block but I did draw it in EQ7 for you. The block finishes at 12 inches. All the strips finish at 1 inch. The center finishes as a 4 inch square. You will have to add your seam allowance. I drew the block in colors of light/dark only for the purpose of showing the different aspects of the block. I would sew the strips and then sub-cut to the size needed.
