I carved a dinosaur head from styrofoam for our styrofoam carving project. After this I covered the dinosaur in plaster then sanded it down as thin as I could get it, I did this step about 15 to 20 times. My goal here was to make the dinosaur as smooth and even as possible while still keeping it as light weight as possible. After I finished with the plaster I dusted the dinosaur off and sprayed him with a clear coat before I finally used acrylic paint to paint him.
