Arrange the colours as you want
After arranging the colours, glue the crayon onto the canvas.
After glueing the crayon, place your (spare) towel/news paper under the canvas then get your hair dryer and put on top of the crayon to make the patten.
If you have a long canvas you can melt more down wards, WARNING: if you melt too much of the crayon you might even mess it, never the less its up to you
