My grand daughter has a facination with labels so for the quilt I recently made her I included serveral and placed them along each edge. Each label was different and included information about the quilt's name, maker, who it was for and when it was completed. One had a message. . . "Grandma loves you."
I've also seen the label included in the center of a block that's pieced into the backing. I think you can do just about anything with your label. It's another way to get creative with your quilting.
