I see it all the time in my neighborhood in Brooklyn...
I know these are little tags, but they still make me smile every time I see them.
Have you seen any knitting graffiti before?
There are several artists and groups that yarn bomb all over the world & the tags will blow your mind.
My favorites are by the artist, Magda Sayeg of Knitta....
See pics here!
I guess I'm just a sucker for public displays of art (pretty much of any kind).
