It will still be damp and the design can be drawn into the plaster, using a sharp stick or pencil. After the plaster has dried overnight, using the end of a plastic spoon or fork, you can carve around the outer lines so that the figures, objects and hieroglyphs stand out in relief. If the plaster is very dry, an exacto knife can be used. After cleaning the plaster work, students can paint it with watercolors. Several coats may be necessary to get a dark color.
Students can also wipe off areas to make the work look aged.
Black outlines can be painted around the objects, if desired. This wooden board protects the plaster, which is heavy, but fragile. Put 2 screw eyes with wire between on the back of the wood. The plaster can now be glued to the board, using Goop or similar mastic. Now hang the finished piece on the wall and enjoy.
