I first heard about this form of public art a few years ago; referred by many different--yarn bombing, yarnbombing, graffiti knitting, guerrilla knitting, or yarnstorming. And I first encountered it on a trip to San Fransisco last summer (click here to see that post with pictures, but this is the first time I've seen any in Buffalo...Nice! Keep it up yarn bombers...I know there has to be more. Thanks for your little glimpse of creative beauty.
