I am really appreciating this thread! Thank you for starting it and to those who have replied. I made my sister a comfort quilt.. it was my first one ever.. and she loves that quilt to pieces... literally, lol. She now keeps it on her recliner back and uses it as a throw. I offered to make her a new one as hers is shredding in many places but she insists she loves her quilt even the way it is. Perhaps I can persuade her to choose one of the suggestions made here. I like the idea of using it inside a new top and back, but she lives in CA and that might make it too heavy.
Anyway, it's good to know there are some options in case she ever decides to let me replace or reuse it.
