Only needs a few tools: Canning jar of your choice with lid and screw on rim, small hammer, 2" common nail, wire cutters, round file, measuring tool, needle nose plyers to bend up the final piece of metal to cut off. You will also need appropriate chain, at least 36" long, and thin wire to mold chain to the jar later when hanging. You will also need appropriate hooks to hang the finished jar light as desired.
Step 1: CAREFULLY Prepare the Lid Opening
Warning to be careful when filing that you do not push the file to the bottom and crack the glass, which is very easy to do without a light hand when using this kind of file. The burrs on the file catch the metal and snag, so you push harder and it gives quickly which can cause you to crack the glass if you are not very careful. Also be very careful of any of the metal edges, filed or not they are very sharp and dangerous!
Step 2: Inserting the Socket Cord Set
I used 36" heavy charm chain to wrap around the lip of the jar, just under the rim of the cap, crossed the chain and brought both pieces to the sides, securing with thin jewelry wire. Please see the photos of the jar light as well as the schematic I wrote up to help, but it does look a little confusing as I read it. (1-2) The initial chain wrap is done after you have woven it with the jewelry wire. (3) You will also be weaving the jewelry wire in with the chain you are bringing back again to meet at each side of the jar, weaving the chain directly to the initial chain wrapped under the lip. (4) Secure and clip the wire at both sides and secure the ends of the chain, crossing a few links, again securing well with wire to hang. (5) You will end up with approximately 12" on either side in which to overlap.
You will need a heavy hook to hang in the ceiling or out from the wall as a sconce as desired. I am just using a large cup hook for this light, but would suggest a plant or light hook if using a larger jar.
I am only using a 7 watt night light in this, but according to the Socket Cord Set, it can take up to a 75 watt max. Be sure to keep the wattage in accordance to the surrounding material of your light fixture to avoid overheating or a fire.
