What if you could get one of those "cheater panels" for the back. I don't know how big your quilt is, but you could add extra to it to make it bigger...then tack it to the already there back. ??? I saw a Strawberry ShortCake panel...
Or, I like PatriceJ's idea of applique` . That would be pretty.
Either way, it would kind of be reversible! :D
Good Luck!!!!
