On the back, I installed a keyhole hook. These hooks are put in so you can efficiently hang them onto a wall. They are available at Home Depot and Lowe's. I used my Dremel to sand out a pocket to the keyhole could be inserted. Fuzzy pic....but you get the point.
Below is another hook I purchased in New Orleans. I painted the plaque brown, added some mosaic tile and finally, the hook.
and there you have it. Some fun, creative and functional hooks for the home.
You can use mosaics, paint, Mod Podge, beads etc for the hooks. They also make great gifts.
