beautiful colors and fabrics. You might check in your area and see if there is a quilt guild or a quilt shop with info about quilt restoration experts nearby who might advise you. If you don't have shattering in the fabrica, you can probably handle them---gently, but still handle them. I'd rather have the treasure you found than a silver do-dad any day. Just think your great-grandmother touched those fabrics, sewed those blocks, thought about how to put them together, went through the same processes you are going through. Lovely connections..
