I really like how this technique looks Surprisingly it is fairly simple to do. First you paint your base coat usually a darker color. Let that completely dry. Add a small amount of water to Elmer glue then paint the glue over the base paint, let the glue get tacky then apply a top color (usually a lighter color) of paint. Let the paint dry. I use a heat gun - holding it 12 or more inches away from the project. You will then start seeing the crackling appear. her are a few projects that i completed.
