We all know about the fabulous IFF Crochet Coral Reef (the press has been outstanding!), but do not miss out on the very crafty Rubbish Vortex as well, created by Helle Jorgensen, a star contributor to the Coral Reef Project.
Jorgensen's complex and mesmerizing vortex of recycled plastic bags thriftily spun into crocheting yarn is a brilliant solution to a menacing global problem.
See the artist's blog, Gooseflesh, for more visuals and details: http://hellejorgensen.typepad.com/gooseflesh/therubbishvortex/index.html
All of the artist's work, including her accessories, are state-of-the-enviro-art.
