1. Spray the crate brown.
2. Rub the edges and slats of the crate with the sides of the candle. The areas where wax is applied will be the areas where the brown paint will show through.
3. Using the brush, paint the crate with color of choice. Paint over the wax application, on all surfaces.
4. Sand the crate, paying special attention to the areas that have been waxed. The paint will sand off easily, exposing the brown paint beneath.
