What would you do if your sweet or savory snacks came in small, colorful, artsy paper boxes like these? Would you eat the treats inside and throw out the box? Of course not!
You could display them on your bookshelf, or make practical use of them for collecting loose buttons and paper clips. But I like to turn them into mail art.
Notice the little purple box (6.5 cm x 4.5 cm; 1 3/4" x 2 1/2 "). It once contained a soft chewy sweet made from purple yams, and it has an etegami-style illustration of purple yams on the cover.
You've probably done something like this before. Maybe you'd like to do an exchange?
