For all the crazy, slightly morbid, yet fun stuff this store has to offer, we've become most enamored of late with quite possibly the most staid, practical product there. The clay pots they have are a study of simplicity, but sometimes that's just what you want from a functional item.
We say let the flowers (or succulents, or herbs) do the talking, and let the pot play a supporting role. The assortment of colors offers some room for creative embellishment, and the many sizes make mixing and matching more fun. Ask for a hole drilled in the bottom for draining capability.
