Unpainted wood. It sits squarely on my shoulders and can be worn by bigger or somewhat smaller people. It looks crooked in this picture because I am keeping the weight off some drying glue by holding it up. I think I will paint it grey blue with "PUBLIC LIBRARY" in dark blue down the side.
I cut myself with an x-acto but didn't look for a bandaid because it didn't hurt. Then when I saw that I was ruining my project I went and got one, and sanded off all the blood.
