I ordered 6 tiles each with a different design for only $1.98 a piece!
We chose Rustoleum spray paint in Antique Copper. A quick coat is all you need and it dries within minutes. Don't worry about applying it evenly, it will add character if some areas are darker than others. The paint will "eat away" at the foam a little which I thought gave it more of an antique look.
Here is the finished product!
