First, remove the hanger pieces from the ornaments and set aside.
Then, add one layer or paint in the dark color as the base color. Let dry about 5 minutes. When you get to the second layer, mix it with a little baking soda and apply it liberally to the ornament. Then let dry 5 minutes.
Next, sponge paint on the lighter color and give it about 30 seconds to dry before rolling it in the cocoa powder. (The only ornaments I didn't roll in the cocoa powder were the white ones. I loved them just the way they were and added the metallic champagne gold paint on them more heavily.)
Brush off the excess powder and then dab on the metallics with the sponges. (I used the gold first in some cases and in others I used it second. In some cases, I used just one color.)
Let dry and spray paint the hangers while drying.
Add the hangers back on and then hang on the tree with hooks, ribbon or twine!
