If you are curious about how to paint them, my art teacher first sketches out the design on a piece of paper and then transfers it over to an overhead transparency. He then shines it onto the flat and pencils the design onto the surface. Finally, he basically does a paint by number (puts dots of color in the areas that need that color) and sets the kids to paint carefully slightly away from the edges. When the kids are done, he finishes by doing all the edges to make it look like a finished product and they look beautiful!
