Textile Totems by the Jafagirls
I think this has to be my favourite pole we've done so far. I like this shot because you can see the other poles and get an idea of the location. And guess what, nobody can complain we are killing a tree (we had several people who were convinced putting knitting on the tree would kill it). It's a strange fad isn't it, but it's fun, it's creative, and it seems to give people a real chuckle.
Flickr has a Urban Knitting Group with photos of knit graffiti around the world. I liked the Knitting Hooligans (what a great name) wristband they put on a Chinese Lion. and how about those red mittens on Lenin :)
