I started signing my quilt labels by hand and use my given name, maiden name, married name plus date & city. Doggone it I want others to know who put so much work in that quilt! Most of mine are given to family & close friend. Just me.
I have two quilts my grandmother made and I had to just guess what year, one was in 1930 something and the other was sometime before her death in 1954. My mother's were the same way. She never signed any of her quilts. I did go back and label these quilts and put my guestimated date on them.
