STEP 1 - Get some wax and melt it on the stove or in a crock pot. Pour it on a glass plate and throw it in the freezer. There are alternative ways to do this, but I wanted a circle, and a glass plate is all ready nonstick. It worked like a charm. You can use leftover candle or batik wax in this case. Both easy to obtain, and easy to find.
STEP 2 - Bust out the tools. You can use wood-carving tools, clay tool, or just strip of hard wire or sheet metal. Be safe. Use wide, rounded tool for young ones. Always cut away from your body. I just cut myself a 1/2" deep between my thumb and forefinger cutting toward myself the other day. It takes a lot of work to keep infection away, and your hand is out of business for at least a week or two if you cut yourself. Cut away from yourself. Wax is easier to cut from wood, so the pressure you use will result in shallower wounds, but that's no excuse. Exercise safety and precaution. Again, cut away from yourself, and make sure no one is on the other side of you.
STEP 3 - Get a thick paint ready. You can use etching ink for this, thinned with turpentine or mix a little water with acrylic. Don't use a water-based paint like watercolor it will not stick to the wax surface and you'll just waste time. You need a thick oil-based paint or a thick acrylic. Use the acrylic quickly, else it will dry on your etching and that would just suck. So get the paint on there quick and place a piece of watercolor paper or other thick absorbent paper on top of your etching with paint.
STEP 4 - Press the etching on paper. Paper facing up. Use fingers or wood. Pull away the paper to reveal a print of your etching. Dry and tear into strips for papier-mâché.
