Orange peels, lemon peels, apple peels ... any peels! These fruity leftovers can easily be recycled into deliciously-scented potpourri. Show your kid how to make her own, and she'll be in for a real treat. The fragrant, netted pouches can be hung in a bedroom, bathroom, or kitchen, to freshen things up. And because you won't end up using chemical-laden sprays, your child will be going green, too!
