Start by mixing Mod Podge with food coloring until you have the color palette of your choice.
Squeeze a generous amount of the Mod Podge mixture into the cut end of your bottle.
Twirl bottle to disperse color all over the inside of the bottle. Repeat with the remaining bottles and place so the excess can drip out. Let them dry overnight.
Wire each bottle with a lighting kit according to package instructions. The one I used had an in-line switch between the plug and the socket base. I didn’t have a need for the switch or the plug since I was going to be direct wiring it to an existing switched circuit.
I cut the wire using wire cutters at the socket side of the switch. I left about two feet of wire to the socket base, but you should test and see what distance looks best in your application.
Run the cut end up through bottle and out the neck of each of the six colored bottle shades. The sockets will fit snuggly up in the taper of the neck of the shade.
Bare the ends of each of the wires using your wire cutters to peel away the plastic coating (there will be 12 wires, hot and a neutral for each lamp or 18 if the kit is wired for a ground).
With the wall switch OFF (throw the service breaker for extra safety) take down the old ceiling light and find the white (neutral), black (hot), and green (ground) wires.Pull them down out of the box and make sure you have enough room to go back with the new wire bundle you're going to create. Combine all the neutral wires from the lamp kits together into one pigtail. DO the same for the hot and the ground if present. Use some electrical tape to help hold them all together while you get ready to connect them to the junction box.
Using an appropriately sized wire nut, connect the white pigtail of the lamp kit to the white (neutral) wire from the ceiling. DO the same with the Black (hot) and ground (green, if present).
Carefully push the wires up into the junction box and allow the weight of the lamps to be carried by the bundled lamp cords over the junction box support bar.
Slide the fixture cover you used from the old light up into place to cover everything. Flip the breaker and the switch on. Put bulbs in the lamps.
