Wall Lettering Review #20192: We used the letters on the back of a clear glass wall-of-water fountain.

I could not find the information about letter colors that I needed for reverse letters applied to the inside of the glass, so I called the DIY office. The employee was very helpful and took care of my order. We received the letters promptly. I won't say they were easy to apply, because it was a rather large layout, but two of us worked together to install them without too much trouble. We are very happy with the way they look.
