You will need:
Tube of 100 percent silicone clear caulking, gloves, mineral spirits, oil-based model paints, scented oil, isopropyl alcohol (if you want to keep using the same bulb for practice), a container to put the silicone in (use an empty yogurt cup with a lid), night light bulbs, or the night light size 5 watt bulbs or the small clear Christmas string bulbs, wire or heavy string for hanging bulbs. Good ventilation is REQUIRED for this project! Use the 100 percent silicone because the fumes are not nearly as bad as the silicone rubber caulking. The silicone rubber caulking give off really bad vinegar type fumes. Use the empty yogurt cup with a lid that way you can seal it and reuse the silicone. •
Add 2 or 3 drops of mineral spirits and stir well with a plastic spoon to thin the silicone a little. You can add a little more mineral spirits later if you find that the silicone is still too thick.
Add color by dipping a toothpick into the paint (oil-based model paint) to scoop out a few drops, and drip them into the silicone. Mix it well with a plastic spoon. Continue adding paint, a few drops at a time, until the shade deepens to your satisfaction. Stir well following each addition. Keep in mind that the color will lighten somewhat when you add fragrance. The color will not be as dark as it appears now when you turn on the lights.
Stir in 3 drops of the scented oil. Stir very well. The oil will make the silicone look slimy at first, but keep stirring until it's thoroughly blended in.
Cut a 12-inch length of wire or heavy string to hang each bulb with after they're dipped. Wire or tie one end to the metal socket of each bulb, and set these aside
Hang the scented silicone bulb up to dry by its string or wire. A towel rack in your kitchen or bathroom is perfect for this. Allow it to dry and cure undisturbed for 3 to 4 hours
Why not make up strings of lights using Fall colors & scents. They really are beautiful strung on the mantel or amoung your fall displays.
