Here's one section complete.
There's a noticable difference between the strength and stability of the new fabrics next to the old. If it was a customer's quilt I'd probably discourage them from trying to do what I'm doing. I'm reminded of the verse in the New Testament that advises against sewing new cloth onto old. But I plan on adding a fresh batt and machine quilting it along the seams to strengthen it. I guess I'm preserving memories as much as anything.
