At first I thought it was a pretty unique idea and very creative but after I gave it some thought I realized if I were a guest I'd have to make a special trip to the bathroom just to get the paint off. Plus, do I really want aunt so and so's fingerprint on my wall for the next 50 years? At some point I'd probably redecorate and put it in my closet where it'd be forgotten.
Is anyone else foregoing this idea?
