I have only made wall hangings, and one pillow. In quilting beginner class it was suggested we always put our names on our quilts. That one was a wall hanging and I embroidered my name in a corner. 2 other small wall hangings I made I put a hand written label on the back.
A suggestion I heard on a Fons & Porter show was to make a muslin case (like a pillow case) for the quilt storage and put some patches of the fabric used in the quilt on it. If it is always washed with the quilt the fabrics will wear the same as the quilt and is available if needed for repairs.
