Erica Bröberg Smith, East Hampton, N.Y.
Cost: $0 in materials; $120 for labor
How She Did It: As she was renovating her home's first floor, architect Erica Bröberg Smith couldn't bear to part with the leftover wide-plank pine flooring she still had on hand. So she turned it into wainscoting on her eat-in kitchen's walls. For a more finished look, her contractor routed a bead to fit between the two horizontal boards and added a simple baseboard and cap. Bröberg Smith still hasn't decided whether to paint or pickle the wood, so in the meantime its natural look goes with just about any decorative scheme she dreams up for this space.
