Have you heard of yarn bombing? would you do it?
Would you call it graffiti or art?

I came across yarn bombing today & thought it seemed very interesting, basically people knit or crochet something & put it in public places.
For example knitting up along rectangle & wrapping it around a tree or a pole. In some cases people have gone as far as covering an entire park bench & covering a red phone booth (in the UK)
Other people knit little "scarves" with flowers, etc attach to them & tie them to the poles street signs are attached to

If you google yarn bombing it will come up with links (Im not sure if I can post them here)

So what are your opinions?
