I love the many options Etsy has to have custom silhouettes made. This pendant by InkStrand is so much fun. I wonder if you could request pink paper and a little glitter? Who knows what could be done?
ModernArtStamps also has a fun idea you should see.
Look at the amazing likeness here. You could have photos taken at the wedding of important members of the wedding party and have silhouettes made of them to decorate your home or to give as gifts. Timeless and beautiful. This etsy artist is PrettyFaces.. don't you love that name?
