I also agree with some of the others that the quilts should be completed and if you have children/grandchildren, they may want one as a momento of grandma. As far as the silk one, I also agree that it shouldn't have anything done to it. Maybe there's a quilt appraiser in your area that you could have a look at the silk top and advise you on what options you have on preserving or displaying it. They also might tell you how to take care of it. Talk to someone in a local quilt guild, they may be able to help you find someone. And at some quilt shows they have appraisers there that could help you.
