This No Poo Zone sign is made from 3/4" pine. I've used exterior acrylic paint and several coats of a clear acrylic. It will hold-up well in all weather conditions. The sign is attached to a pointed wood stake. It is a small sign measuring 11 1/2" long x 9" tall. It's a nice way to get your point across to all the local pet walkers. Hopefully , it will do the trick!
