New Switch Plates
One of the easiest ways to update the look in your room is to update the light switches. It's usually the first thing you reach for when you walk into a room, so a new switch plate will surely get noticed.
Find a decorative switch plate that will fit the design of the rest of your room. Replace a plastic plate with one of brass, copper or chrome for a more refined and decorative look. There are even switch plates that have textured designs or have pretty color schemes.
Using a screwdriver, unscrew the old plate, then simply screw in the new plate into the same holes in the switch.
