Thanks for your help. I'm not sure what the stains are. The quilt was in a plastic bag and folded for years, so my guess is acid or mildew only they are light brown in color. I will definately bind it first so thanks for telling me do this. I thought about stretching it out and using a spot remover.
The quilt is close to 100 years old and belongs to my husbands 1st cousin. Their Great Aunt made it and I am trying to finish it for her to give to her Great-Grandaughter. So yes it is pretty precious
