You will need: Per one masterpiece: 12"x16" Canvas, Box of 64 Crayons, Glue Gun & Glue Sticks, Heat gun.
Glue the crayons in the arrangement you like. Have someone hold back of canvas on a tilt. Heat to desired result from left to right, but from center of crayon & down on the canvas. (If you start from the top the crayon will melt up like a volcano... avoid- not a good look)
For a more lasting piece, heat wax even on the canvas without thick drips at the bottom because it will crack after time.
