Technique 1: Crayon Resist
Using a white crayon, draw where you do not want the watercolor paint to stick. This technique is great for outlining your objects or adding texture to your painting. After the crayon is drawn, a layer of watercolor is applied to the paper. You can add it section by section or one continuous application. Where you put the crayon the paint will not stick, creating an image.
You can use a white oil pastels instead or even a glue stick.
