You just can't see the problem in the picture. However, if you really dislike it, calm down...and take out the seam ripper and pull the top off. Iron it flat, and use new batting.
If you just can bear to do that, could you make a tablerunner? Are there parts of it that you could salvage? Could you bear to pull out enough of the quilt to make a runner? (and maybe placemats later)
