Pressure Variations
Vary the pressure on a crayon by pressing hard or lightly to create a deeper or lighter color. Vary the pressure in the same scene to create a sense of depth or distance. Use light pressure to create shadows and heavy pressure to create visual dominance.
Crayon Etching
Cover a thick layer of crayon with a dense layer of black crayon. Use a paper clip or toothpick to scratch lines through the top layer to reveal colorful layers underneath.
Crayon Resist
Color lines and shapes of the artwork heavily, then cover with watercolor or paint. The waxy crayon will "pop" though the painted surface. Experiment with thinning the watercolor with water.
Texture Rubbings
Place a piece of paper on top of flat textural materials, such as leaves, a plastic dish or door mat, sandpaper, a screen, netting or latch hook mats. Rub over the paper with the side of an unwrapped crayon. Watch the textures and patterns appear.
