Also known as: Yarnbombing [it]originated in the United States with groups such as Texas-based Knitta, which frustrated with their piles of unfinished sweaters, adopted hip-hop style monikers such as Loop-Dogg, P-Knitty and The Notorious N.I.T. and turned their knitting into a seditious gesture, juxtaposing craft and vandalism.
I was pleasently surprised to see 'Knit Art' on this bridge in Prague:
The purpose behind "soft graffiti" is not to create something practical but to add a little novelty to life's humdrum routine along with the chance to reconnect with the urban environment.
Have you seen any Knit Art around?
