A couple of ladies have asked. I based what I am doing on a couple of web sites I visited, then drafted the main block onto paper; traced off the 3 sub blocks, added 1/4" seam allowance, then traced onto very lightweight interfacing and foundation pieced. I don't purchase any of the specialist rulers, I just try and work things out myself. (sometimes successfully LOL)
