Total Art Soul has a GREAT idea for putting polystyrene containers to good use after you've emptied them of your takeout. Use them for printing. The super-simple process could be used to make art, greeting cards or even t-shirts. Besides the canvas/paper/fabric of your choosing and a polystyrene container, you'll need a pencil, paint or ink and a small roller. To see how it all comes together, visit Total Art Soul.
