Gutter strainers -- the wire cages that filter leaves and debris washed off the roof -- also make great orchid pots, providing the plants with excellent aeration and drainage.
Buy an inexpensive copper strainer at a hardware store. Using a pair of light pliers, bend the spindly legs of the strainer into decorative loops around the top (the loops also offer a way to hang the orchid if you like). Soak sphagnum moss (available at garden centers) in water, pack into the strainer, and then put in the orchid. Pack with more moss for a snug fit, and give it a hearty watering in the sink. Let the moss drain completely before placing the plant in a bowl.
