I don't know anything about knitting, but as an avid tracker of both low-impact graffiti and puns, I was delighted to find this blog: "Knitta Please." (Thanks for the tip, BuboBlog Berkeley correspondent Lynn.)
It spotlights the burgeoning trend of yarnbombing — that's where people knit cozies and other adornments for public objects. (There's also a blog called Yarnbombing.)
You may recall that some East Bay "guerrilla knitters" foisted their handicraft on a sculpture earlier this year.
I can only imagine what the world would be like if everyone expressed themselves this way. For one, a Footlocker in Oakland would have a nice window-sweater right now.
