Hey, just found a website that explains how to piece that block. You have to scroll down to the middle of the page for instructions. (although I don't think I'd do the triangles how they explained them...to much stretchy bias edge for my liking...but you certainly could do them like that...with spray starch to keep your pieces from stretching.)
