My motto is "Why recycle when you can re-use!"
Do you have trouble keeping crayons organized? If so, here is simple littletip. You know those plastic parmesan cheese shakers? Well, they can be used as crayon holders. Littles can pop up the shaker opening and shake out their crayons. Then when they are done coloring, they can unscrew the top and put away the crayons.
It works quite nicely.
