These gnomes are made using a cork, which you cover with a crochet ‘skin’. There is a space for the face, which you draw in with a pen.

You will need:
Small amounts of yarn: for example red for hat, white for hair, blue for top, brown for trousers.
Black yarn for mouth.
A cork, approx 1.75” (4.5cm) long.
Black permanent marker pen (Sharpie).

You can also make Knights (http://lucyravenscar.blogspot.co.uk/2010/02/cork-and-croc...) and Ninjas (http://lucyravenscar.blogspot.co.uk/2010/02/cork-and-croc...) using the same technique.
