I made a bunch of mini pillows with a hidden pouch in each of them for my nephew to "sell" at school for a economics class on supply and demand. They bartered and traded items that they had to make or had to be homemade. It taught them free market principles. He sold out really fast. The kids loved them because they could stash their ipods or cash in the little pouch. Each item had to cost less than a dollar to make, so my nephew came home with a bunch of odd items that didn't even come close to being as cool as our little pillows.
