To get my wedding vail back to white, my father told me to go buy ivory soap, the old bar kind, and put a heavy lather on it and let it soak for a day or two. Dag if he wasn't right, it came out beautifully. You may want to try that. Now I always keep some around the house. AS for as a quilt. You can look at some of the patterns on line that used old hankie's. They may give you some inspirations.
