Maybe you aren't well versed in swinging a hammer or sawing some trim, but certainly everyone can tighten a screw!
New/updated/decorative switch plates are a REALLY easy household project that can have a great impact toward updating the look of a home or continuing a specialized theme of a room.
Most of mine have been switched to brushed nickle plates. My girls each chose one that matches their themed rooms. My biggest tip is to look into your local come improvement stores instead of furniture/decorative stores. You would be amazed at the selection and the prices are much more competitive!
