Thanks to all. I also think it is beautiful and can't wait to sleep under it. After a good night sleep, I think I have a plan. I am going to create a 6" square template and mark the back of the top and fudge around the melons so I won't struggle as much trying to get it to line up. I know that some of the arches have already warped and I want the squares to look right since they will be more noticeable. Once I quilt it the misalignment shouldn't show up as much. Tartan the applique idea is good but I would like to stay as true to my GM's work as possible. I'll keep you all posted but will welcome as many ideas as you can give.
Happy Quilting,
Tami
