This looks like a fun middle school lesson - Shoe Sculpture with collage:

"Students were to each create a sculpture of a shoe decoupaged with pictures
depicting the popular culture and history of the time when the shoe
was fashionable."
I must remember to check the School Arts Site each month.... I have
missed some "goodies". Be sure to send in your subscription request so
you can get April issue. Keith Vieth (Oridinary to Extraordinary
author) will have an article on coil built masks.
