Step 2: The Wick Holder
Take your metal bottle cap and use a nail and hammer to make a big hole in the middle for the wick. Make sure it's big enough for your wick, but small enough to actually hold it tight.
I also made 2 smaller holes on the edge of the cap (on opposite sides) for the wire to go through. You can probably see those better in the following pics.
* I read that if you are using galvanized wire, you need to rub it well with sand paper 1st. I don't remember why exactly, but I thought I should mention it.
I took 2 strips of wire and put each end through a small hole on the side of the cap. The length of wire depends on the size of your jar and how high you will be filling it with oil. I only wanted mine to be about half full bc I wanted the flame to stay inside the jar.

Here is the bottom of the wick holder. After I got the wire through the sides, I put it down into the jar so that it was at the level of where I wanted the oil to be. I then started to form the wire around the jar so that it fit as snug as possible. You want the wick to stay in place (duh) but you also want easy access to it. When the wick gets too low, you want to be able to easily get it out and pull it up with tweezers. I left the side "wick holder handles" a little long bc it seemed to stabilize the wick holder better.
Now you can feed your wick up through the center hole.
