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
