Once the chopstick is completely dry, paint it dark brown (I used acrylic brown paint) and let that coat dry. Apply another coat of brown paint if necessary.
Now to give it a little more depth, use black paint to brush it lightly (don’t cover all the brown) and push it all down into the cracks and crevices.
Once it is all dry take gold acrylic paint and lightly brush the tops of the ridges lightly with gold. Keep playing around with it. You can always repaint it if needed and start all over! These are such a fun and inexpensive party favor.
