your hand inside a sock and form a mouth by pushing the sock in between
your fingers and thumb. With a felt pen, lightly mark where you think
the eyes, nose and other features should be. Remove your hand and make
the facial features by colouring them in with felt pens. Alternatively
you may sew on things like a button for the nose, some strips of material
for a tongue and ears. Some wool makes good hair and then pass wool through
the same point several times for the eyes.
