Today it's all about art in your environment that you probably don't notice. I drive down the same street nearly every day and never noticed it until Susan told me to look for it: A Yarn Bombing! Since then she's spotted only one other here in Austin (second set of photos), although there are some blogs out there that mention different ones.
There are various names for it: Yarn Bombing, Guerilla Knitting, Yarn Storming, Yarn Graffiti, etc. All make me smile when I think of them because yarn is a nice soft thing and makes you think of your granny or your favorite sweater or socks.
I don't think it's bad, I think it's good. It doesn't hurt the environment, can be easily removed, and it's subtle. It is art, just as much as Andy Goldsworthy and many others make environmental art. And it probably makes you smile.
The poles in these pictures were just old sign posts where the sign had been no longer necessary and was removed. Since the city sinks these poles in concrete it is obviously too much trouble to remove the poles so they just leave them there. Naked. But now these poles have their own knitted sweaters! Way cool.
In Austin: The first one is on Robert E. Lee, just past the Umlauf Center. The second one is on Barton Springs Road at Stratford.
