International Yarn Bombing Day

They're showing up everywhere, like some kind of psychedelically colorful mushroom that grows sock-like over surfaces like trees and scaffolding and even bike racks.

Somewhere, somehow, these normal everyday objects have suddenly become ensconced in an odd wooly growth in amazing patterns.

The skill varies widely from incredibly new to fantastically intricate, the thickness of the yarn from pencil-lead thin to thick as the pencil itself. International Yarn Bombing Day is when fiber-freaks from around the world go on a knitting rampage to embrace the world in warm fuzzy comfort. Grab your needles and go forth noble kneedler, and stitch!
