I have a huge respect for public art, am engaged by thoughtful street art, but have no respect for taggers (c'mon, guys; it's 2010). So, the idea of renegade public crafting is exactly the kind of thing that gets me jazzed.
Yarn bombing, a.k.a. graffiti knitting, is the act of an artist who seeks to improve an urban landscape by thoughtfully placing handmade fiberarts in a public place. These serve to beautify and engage, and are left indefinitely, or until the authorities have the piece removed.
(That's not really an official definition, but sounds pretty good, yeah?)
Our friend Dana from Yellowtrace has assembled a pretty rocking collection of such works. All of them are engaging to look at - the colors against the browns and grays of the street are amazing, but many also make public statements.
Dana also points out a book on the subject, Yarn Bombing: The Art of Crochet and Knit Graffiti.
