The project was pretty easy and didn't take a lot of time. We spent an afternoon looking for a variety of vintage mason jars at the local antique mall and getting the electrical supplies. Then it took a couple hours the following morning to install.
I bought three hanging light kits from Lowes and also a ceiling plate which I drilled holes in to hang the cords through. I simply used a hammer and nail to make the holes in the tin lids of the mason jars and used a pair of tin snips to clip off any sharp points. Then it's a just a quick lighting fixture install using the red twist-on connectors that allow you to connect up to 4 wires together (or you could call an electrician!). Done!
