Step one: Begin by sketching the facet lines as shown. They don’t have to be perfect.
Step two: Mix up six shades of the color of your choosing using black and white paint. Just remember that the black paint goes further when mixed than the white.
Step three: Use the fine tip brush to carefully paint inside your sketched facet lines. Start with the mid-tone in the middle, and the lightest shade all the way to the left. Work your way around as shown. We paint the edges and the back in the mid-tone as well.
Try out some other colors and use them in all sorts of ways…jewelry, keychains, napkin rings. How would you put them to use?
