I made a valance out of ours. I really just stitched together 2 pieces of bumper (I even left them quilted) and changed out the ties on one end to loops for the curtain rod. I'm considering cutting out some of the remaining sections and framing them as wall art. I haven't decided if our walls are getting too crowded, though (we have a small-ish nursery).
If you Google it, you will find some blogs with ideas. Depending on how crafty you are, you can cut out parts of the designs to make little dolls or soft books, too.
