Paint the rocks red with 3 coats of red paint using the 1 inch chip paint brush, allowing the paint to dry between each coat. You may use a hair dryer to speed up the drying time.
Use the ¼" flat angled artist brush to paint the top wider part of the rock green, then paint the “leaves” of the berry.
Use the tiny foam applicator brush (or Q-tip) to paint the yellow “seeds” of the berry, by just dabbing the brush on the rock.
Make a tiny dab of black paint above the yellow seed.
Spray the rocks with the Krylon Clear Coating, and allow a couple of hours to completely dry.
