I agree with ptquilts. The leaded silk is so fragile that it would just disintegrate with any pressure on it. I would baste tulle over the pieces that are shredded and put a back on it. The hanging sleeve would have to be the with of the quilt to make sure that there is equal pressure. I bet this quilt is heavy. Be sure that there is a label that details what was done to this top. Also if it is going to be hung, it should be kept out of sunlight.
