We drink a lot of Crystal Light in our family. The cylindrical containers
are a wonderful size for sorting pencils, brishes, etc. The labels come
off easily revealing aethetically-pleasant, translucent cylinders that can
be hot-glued together in pleasing arrangements (the tops are useful, too,
although they do get lost sometimes). I have used many glued together to
keep brushes and clay tools sorted. I have also made sets of markers from
class packs...about eight will fit in each. I have also made specialized
sets of Prismacolors including erasers and sharpeners for advanced students.
As summer approaches, you might put out the call for these containers.
