So the question really is: do you want to repair these quilts? I have relatives who are smokers, and I still love them. If one of my smoking relatives were having this problem, I think what I'd do is make sure there was a smoke detector in the room for a real fire. And then I'd find some kind of material that doesn't burn through, and I'd make a blanket for her out of that material to put over her bedding, so the bedding doesn't catch on fire or make holes in the quilts. And then I'd patch the quilts as nicely as possible. And I'd do it because I loved her.
