I add my label underneath the side & bottom binding. That leaves only two sides to sew on. I usually hand sew it on but if I am in a really hurry, like with the kitty quilts, I fuse it on, use a deco stitch for the edges, then quilt through it with the grid quilting. This method doesn't put it under the binding but I have been attaching the binding on these by machine for time reasons. I have been writing out the labels w/Pigma Pens & heat setting w/iron until I can figure out how to embroider them with the embroidery machine.
