I've been a long-time instructable consumer, but this is my first time creating one so go easy on me please! Oh also, if hanging fixtures aren't your thing there are a bunch of other cool jar light 'ibles like this one .
Step 1: Tools & Materials
big jar - i used a bell mason jar from the hardware store $13 for 12 jars so... ~$1 per jar
pre-assembled light socket and cord - i used the "hemma" from ikea - $6.99
light bulb that fits through in the jar
some sort of cutting implement. I ended up using an exacto knife, but i'm sure there are better ways
Step 2: Cut the hole
now for the cutting part. at first i tried to use a hole cutter on my drill, but this didn't really work out so well. I ended up just using a box cutter to cut through the lid. keep in mind that the hole doesn't have to be perfect because it won't show and you can adjust everything when you are screwing in the socket. all you need to do is make sure that the end of the light socket can fit through the hole.
