You don't need carafes and matching tumblers to provide overnight guests with water. Simply fill a tall, narrow glass, and cover it with a shorter, wider tumbler to keep out dust. Set the glasses on a small tray on the nightstand to catch any drips. Houseguests can flip over the top glass and pour themselves water or sip directly from the taller glass.
