Joe Winterbourne loves the clothes his mother made for him. At school, everyone calls him Mr. Recycling. His hat is made from used umbrella. His shoes are made from used rugs. His trousers used to be his school bags. And look at his watch! It used to be his clock! He made it smaller and ties it around his wrist as a watch.
