* Acrylic paint in various shades of green and blue
* A paintbrush
* A cup of water
* A small piece of sandpaper
* A clear coat sealer
Instructions:
1. Choose your shades of green and blue. Verdigris can vary in color from light green to deep blue-green. Choose the shades that you think will best imitate the desired effect.
2. Mix the paint. In a cup or bowl, mix the green and blue acrylic paints together until you achieve the desired color. Add a small amount of water to thin the paint, if necessary.
3. Brush on the paint. Use the paintbrush to apply the paint to the surface of your choice. Work in small sections, and use a light touch. Allow the paint to dry completely.
4. Sand the paint. Once the paint is dry, sand it lightly with the sandpaper. This will help to create a more realistic patina effect.
5. Apply a clear coat sealer. To protect the paint and extend its durability, apply a clear coat sealer over the entire surface.
