Sounds like using them in a quilt would be a great use for them. I would not recommend that you cut any of them, simply preserve them because of age. Perhaps you could use the table cloths for the center part of a quilt and the napkins scattered around the center. Maybe make two quilts if they are different, and use them as wall hangings, maybe one in your dinning area, or as a quilted table cloth. I think that would be so neat to do something like that. I have lots of old hankies that belonged to my grandmother and great grandmother, that I plan (when time permits) to make into a quilt. I want to use them as they are and frame them, problem is there are so many different colors, I have not decided just what color to use with them all. But I will. Good luck in whatever you do with your treasures.
