There have been oodles of art which has been created with knitting, from supercars to plates of food. I have also discovered these zombies which I think are really funny and very clever. They are part of the handknitted Zombie campaign from UK-based Hannah Simpson.
Obsessed with the 1978 classic Dawn of the Dead, the movie was her inspiration to create a series of hand knitted zombies. She has also done a series featuring Simon Pegg and Shaun of the Dead - the zombie tribute movie.
Hannah's Zombies can be found on etsy, of course, and she has also printed a series of cards featuring images of her knitted buddies.
