This is an example I made for an Awareness Through Art project I'm doing with life skills, emotional support, and autistic kids at my old school. We're creating an oceanscape to publicize the amount of plastic in the oceans. There will be about 30 of these - all different sizes, shapes, and colors, in the final installation. I'm wondering whether the postal service would send one of these through as is or would it require a wrapping/envelope? I will take one to the P.O. and inquire...to be continued.
