I have started incorporating my labels into the backing of my quilts and quilting them into the quilt, so they cannot be re-gifted easily or if stolen, the identity will be hard to hide. If I am giving a quilt to someone who is ignorant of the value of the quilt, I'll figure out a way to tell them that if someone they know is interested in a quilt of about the same size, I'll be happy to make one for them but tell them that the price will start at $500 and go up. That way they have an understanding of the value of the quilt, and I just might get another quilt sold!
