I decided to look it up and it is called yarn bombing or graffiti knitting - and is a type of street art. Joe says he sees it a lot in the Kensington area of the city and I will be there next weekend for Market Collective so am going to take a bit of a walk around to try to find some more.

Have you ever seen yarn bombs in your city?
