I lsbel every quilt. Sometimes I make a label, sometimes I use one of the ones that come printed on fabric. It doesn't matter how you do it, just so you do it. I have a bunch of my mother's quilts and she didn't sign them. Now we don't know when she made them and if they ever get out of the immediate family they won't even know who made them. You can also print them on your inkjet printer, but do take the time to label them.
