I'm sorry I don't know how to attach pictures to my replies so I would end starting a new thread, but these arrowhead blocks are made by starting 2 inches down from the top right corner, sew down the side, pivot and sew across the bottom. Turn the block, starting 2 inches down from the opposiste corner, sew down the side and across the bottom. Cut the block on the diagonal thru the sewn corners. Stack the triangles, cut 2 inches from the long side and another 2 inches along the bottom. This will give you presewn pieces that form the block. This is not my method, I don't know the origin of it. I will attempt a tutorial, but I have only very basic computer skills. Tammy
