53 Scrapbooking Techniques: Wax Resist
You probably experimented with the technique of wax resist in elementary school.
You take a clear or white crayon, draw a pattern, write words, create a background, and then color over the design element with acrylic paints, Lumiere, walnut ink, etc.
The wax will resist the paint and show through, resulting in a great design. Wax resist makes a creative background for children's artwork as well as children's scrapbooks.
