Build a chic and affordable wooden planter box with cuts of spruce, nails and a few coats of dramatic grey paint, with instructions from H&H stylist Peter Paquette. The rectangular box houses three basic 12″ plastic pots, and would look great on a back deck or as a divider wall on a cramped condo balcony. Fill it with fresh greenery such as evergreens, flowering pots, or ferns.
