Have you checked out John Flynn's site. he has engineered a template set that makes doing a dwr so easy. I bought his king size and made one for my brother in less than a month. His technique requires you to cut strips, sew together, put on a line marker on your machine to guide then sew at angle then use templates to cut the football shape and center arcs. Was so easy, matching points at the peaks was real easy. I had no issues making it. Check it out, John Flynn in Billings, Montana.
