Coral and Shell Mirror.. I love this and might pay as much as $500.00?? for it but the cleanabiliety factor . It would look so much better on a darker wall which I've had in the past. Sq. would be a good shape also,
When I decorate with seashells, I use ones that I've gathered on the beach myself or that I find at garage sales. I never buy them from stores because I'm so afraid they're dredging them from the ocean. You can also buy faux coral in pet shops.
