While most parents would slip a note into their kids' lunch bags,David Laferriere goes a step further. A graphic designer and illustrator, David uses a Sharpie marker to draw on his kids' sandwich bags. Each drawing is done just after he has made the sandwich. He takes a picture and posts to flickr. His kids don't see the drawing until it is lunchtime.
