Colored pencils are an easy way to add surprisingly durable color to metal jewelry components. As long as you prepare the metal properly, use artist-quality materials, and seal the finish, you can exert complete control over the final color of your piece.
Use coarse-grit sandpaper (at least 80-grit) to sand
the metal thoroughly with a circular motion (Figure 1)
. Make sure there are no smooth spots left on your metal.
