Heart matting over framed map

I recently took down a tapestry in my bathroom, which I loved, and gave it away as a gift. (first posted 11/12/11)  I'm considering new ideas for the wall space and found this to be simple and meaningful.  The heart could be cut from any white paper.  The maps are a neat idea behind the heart, but I am wondering if I could change out the piece behind with other ideas.
