They might not look like it now, but all of these lamp shades began their existence as plastic drinking bottles. Eco-designer Sarah Turner is the talent behind them. Thirty 500 ml are used to make Cola 30, pictured above. The Lily lamps are constructed of 2-liter drink bottles. (Sprite, to be specific.)
And this is the rather retro Daisy Lamp, again made of 2-liter drinking bottles. (For some reason, I had to keep reminding myself that as I perused Sarah's portfolio. Amazing.)
