Just to pass along a tip I saw the other day from a teacher friend. She
takes tennis lessons and has her tennis instructor save all the plastic,
see-through tennis ball containers (of three balls each). These are large
enough to hold a full box of colored pencils (unboxed, of course, duh) and
possibly enough room to throw in a handheld pencil sharperner or two...plus
you can see through it clearly. It also has a top attached which doesn't
break easily. Great tip. Wish "I" had thought of it myself!
