I have taken some of my Mom's hankies - backed them, then used lightweight batting and a backing and hand quilted them. It was really thin, but turned out fairly well. Photo isn't too good, but should be good enough to get the idea. Then I quilted some hand embroidered doilies - the fabric was also a little thin. They came out really well. Someone had spent a lot of time doing the embroidery and then the crochet edging and just couldn't stand to see them not preserved in some way.
