Some of the nicest antiques turn up among dusty odds and ends in junk shops. These vintage metal and porcelain coat hooks were once considered mundane household objects. But their graceful shapes are much more attractive than the lines of their plain modern counterparts. Since old metal has a mellow patina that clashes with shiny new screws, darken screws to match the hooks. Simply place brass or steel screws along with a dish of ammonia in an airtight plastic bag. In about 15 minutes, the fumes will have tarnished the metal; remove screws when they've achieved the desired appearance.
