I have only been quilting 9 years, but I label the quilts I give as gifts & keep for me. I have 5 quilts I inherited from my grandmother - NO labels. I 'think' her mother made them, but who know. If there was even someone's initials hidden in the binding, I would probably know who made them. I have had 2 appraised and the appraiser said to label them with what I know, that the history begins with me.
