While surfing the web this morning, I came across this little piece at Greenopolis.
Titled "18 Green DIY Lamps You Can Make Before Dark," it's a collection of links and photos with inspiration, directions, or links to kits for lighting made from repurposed around-the-house (mostly) materials.
Definitely be sure to get a load of my two favorites, the cardboard fairy lights (pictured here), and the plastic cutlery chandelier.
