I label my quilts with my first name, maiden name, and last name, date finished, city, and occasion for which it was made. I want whichever family member gets one of my quilts (on down the line), will know both family names. My quilts are not heirloom quality, but to me they are (lol). I have my grandmothers quilt (she was born in 1873, and had my father when she was 43 in 1916), and the quilt is not labeled and it would have been so nice if it had some sort of label and date made. I don't think it matters what sort of quilt it is, but that it was made from the heart and made from their relative's hands.
