Several years ago I made a jeans and flannel shirt quilt for my son. Used a pocket from the jeans for a pocket on the back to put remotes, etc. into. Also wrote on it for the label. I like that idea of putting a zipper as it would be securely closed though. A pocket would be good also for a quilt with a story. Write the story for inclusion so it doesn't become lost from the quilt as time goes on.
