Black and white paint
Step 1: Paint the Inside of the Bulb
Pour paint inside the bulb and evenly coat the inside, covering the entire inside of the bulb with white paint. The inside may take 24 to 48 hours to dry on the inside. The drying process depends on how much paints has been put inside the bulb.
Step 2: Paint the Outside
Paint the outside of the bulb with any design you want. This may take 2 to 3 hours for this paint to dry.
Step 3: Cover in Modge Podge
Cover the black paint in dodge dodge. This will keep the black paint on.
Step 4: All Done
After the modge podge dries, your bulb is all done. I added white ribbon to mine so that I could put mine of my tree nicely but that is totally up to you.
