Tell us about yourself!
It's been awhile since I've done this, but crayons can be used as the "resistive medium." When I was in first grade, back in 1966, my teacher had us draw a Halloween picture with crayons using bright colors, no black. After we finished our masterpieces, we washed the whole thing with black watercolor. The result was our landscape turned into a night picture. I doubt the results were spectacular at the age of five or six, but after 50 years I still remember it.
