I saw something quite ingenious while I was at the Northwest Flower & Garden Show earlier this month. The orchid folks had taken picture frames, nailed wire to the back of them, and then hung small pots of orchids from it.
Besides looking cool, it seems like a very clever way to keep one's orchids all together without taking up much room.
Orchids are typically grown in bark so the pots hardly weigh anything. That means you could hang a whole bunch of them and still have a very light frame. Pretty cool, huh?
