8Step 1. Buy and Cut Drywall A 4 ft. by 8 ft. piece of drywall should be cut into 12" (or smaller) squares. This can be done by scoring the drywall on the "right" side with a boxcutter, and then "snapping" it along the score line. I use a boxcutter on the reverse side to cut through the remaining paper that held the squares together
9A Tip!!!Students can glue their square of drywall (back side down) to a piece of cardboard the same size. This will help to make sure that the piece stays together, even if it cracks while they are working on it.
10Students should use sponges (wet, but not dripping) to soften and remove the paper on the front of the board. This takes a lot of time and patience!
11Creating a design in pencil Students have created designs on newsprint or scrap paper. I have them transfer these designs in pencil onto their clean plaster surfaces. I encourage students to keep their designs simple and to keep raised lines or raised areas at least ½” thick due to the fragile nature of the plaster
12Students use a small carving tool to outline their design.
13Gum ErasersI have found that the junky 1” gum erasers that are often found in art rooms are really helpful in helping take the paper off. Just use it in a circular motion and you will see the paper magically come off and the smooth pristine plaster surface shining through!!!
14TipAs they begin to carve, students should keep the surface slightly damp. This will make the drywall easier to carve and it seems to reduce chipping. If they get it too wet, however, it is much more likely to crack.
15Once that is done, they should switch to a larger tool to more quickly remove areas that they intend to cut away.
19More Helpful HintsAdd the plaster powder that is produced from the carving to watered down elmer’s glue to make a very thick, plastery paste that can be used to fill in cracks and repair breaks.Put down newspaper on tables, so that cleanup is easy.Use a bucket to rinse out sponges and clean tools. Plaster will clog your sinks.Don’t let students carve too deep. It will make the drywall too fragile. It will break.

Spray paint Students can experiment on scrap pieces of drywall to determine surface treatments that will enhance their pieces.Acrylic PaintWatercolorInk WashesShoepolish (rub on and off to create stain effect).Spray paintMetallic gold leaf, paints, etc…
