According to Wikipedia:
Yarn bombing, yarnbombing, yarnstorming, guerrilla knitting, urban knitting or graffiti knitting is a type of graffiti or street art that employs colorful displays of knitted or crocheted yarn or fibre rather than paint or chalk.
This idea has piqued my interest... Dare I say I am inspired?! I am not much of a knitter and have never made it much beyond the scarf and potholder phase but I think that much skill would suffice for this type of adventure.
Some of these projects are a bit beyond my capabilities although |I suppose a person could do the bike and then just wheel it to the site and chain it there?
Some very adventurous ladies in Whitehorse yarnbombed a vintage aircraft!
Basically, any public installation seems to be fair game. I can't help thinking ahead to next September when the Embroiderers' Association of Canada has it's Stitch in Public Day. What could be more fun??
