First, attach the light bulb to the pendant light kit.
Then, attach the light kit to your mason jar and you are done!
Notes
If you want to add more color to a room, try colored mason jars for a different effect.CAUTION: I used a very low wattage bulb to prevent the jar from getting too hot. You can also get open bottom mason jars that help let the heat escape. You can even try cutting the bottoms off of the jar yourself.
