When my mother passed away we went through her quilts an found an old quilt with no label, however we were able to identify the maker because she used a piece of backing that had a dyeing flaw across the top. My mother would never have used such a piece of fabric, but Aunt Elsie would because she hated to waste anything so we knew who made it. Otherwise it would have been passed through the family and no one would have had any idea who the maker was.
