This is one of my Roundtoit Quilts that I hope to make. I used to have the templates from Sharlene Jorgensen, but some "idiot" in my family threw them out. I was so not happy. Anyway, I did do a trial on the templates and found that the smaller, I think it's 28 mm, rotary cutter worked best and is what she recommended when I watched her video. I think a scrappy DWR would be gorgeous, but I might keep the A and B pieces one color each to unify the quilt. Can't wait to see a picture. Tartan has some good advice for you, as well as Bree 123.
