One of the things my boys love are video games, a current favorite is Little Big Planet. They designed their own sackboys on paper, instead of a screen.
First they made crayon rubbings with texture plates for their sack's textile skin.
Then they dressed their sack boy, using oil pastels
Joaquin's is Simon Sack, a character from one of his stories
Atlas' is the Monkey King
Oliver's
Joaquin also drew his own sackboy, this one is a jade goyle sackboy, from the book Reckless, by Cornelia Funke.
