Bronze, of course, is the way to go if you can afford it. The translucent quality of the material is amazing! Plus, there is always a difference with faux vs. the real thing; no matter how good the forgery.
If you are looking for something on a smaller budget however, resin is the way to go. I made this "bronze tile" for the bathroom a little bit ago, and everyone always comments on it. All it took was a little bit of creativity with clay, a little bit of mold making and there you have it.
A lot of time you simply can't find that special piece you're looking for, or it's in the wrong size. That's when custom artwork comes into play. Plus, custom art is a nice way of having something different for your home... something no one else has. You can do it yourself or find a local artist to help you out. It's a great way to get inspired and creative. Really! I know.
