This is probably my favorite DIY project I've done so far. The fireplace originally was just white tile. I found these "stones" at Lowe's. They are called Airstone and they are made out of recycled wine bottles. I was able to cut them with a hack saw and they were glued to the tile with Liquid Nail. This project was easy on the wallet, easy to do and produced amazing results. Check out all the before and after photos!
