I love this plastic bottle top lampshade from espirit cabane. Elegent in all white plastic lids from milk or drink bottles, I can equally envisage a "crazy" shade made from a variety of colours.
How about a hanging plastic lid curtain? Use the same technique to tie the plastic bottle lids together and create a colourful room divider (technique is on the original tutorial page). What a fantastic way to keep plastic lids out of landfill and off our coral reefs.
Are you aware that plastic lids have fast eclipsed cigarette butts on the world's beaches? Thanks for being responsible and getting off your butt to reuse your plastic waste rather than adding to the floating islands of plastic we have created. Read more about that here.
