This is a practise invented by the surrealists to add an element of chance.

I created characters with peers, then turn one I worked on into a final character in full colour in photoshop.

Start by drawing a head and a neck. Fold a flap so that it hides the drawing for the next person. Pass onto the next person, they draw shoulders, arms, and torso, fold a flap to hide the drawing just leave the ends of the torso poking out, and pass the paper to next person.

Next person draws hips legs and feet. Fold and pass onto next person.

My idea comes from the new Gucci Ghost Accessories.
