Change the cover color or style by painting it a bold color if the fixture is made of a hard material such as glass or metal. A bold color can accent a room's decor. For a patterned look, add decals to the fixture. Bird or flower decals can add a whimsical touch to the fixture and cast shadows when the light is on, giving a room greater ambiance. This option is best for large pendant or fluorescent fixtures because less heat is absorbed by the light.
Remove the shade and cover it in an attractive fabric found at local craft or antique stores. Try speciality paper with eye-catching patterns and colors found at supply stores. If you have old doilies, tack them onto the shade for a textured pattern with a touch of "granny chic." If you're handy with a needle, embroider a design or scene on the shade. Or, try wrapping silk ribbons in several colors and wrapping them around the shade. Adhere ribbons to the shade with fabric glue.
Replace an outdated lighting fixture on a wall or ceiling with an "unexpected" element. Refashion the fixture with a mason jar as a cover. Screw the lid onto the jar and the lid can become a platform to thread through the light socket. Do something similar by drilling a hole into the bottom of a coffee mug for an quirky overhead pendant fixture in a kitchen or dining room.
Some fixtures can get a face lift just by paring them down a simpler state. Remove the fringe and any trim from an outdated lampshade with a seam ripper for a sleeker lighting accent. Recover table and floor lamps covered with soft materials with other materials such as parchment, linen or canvas-colored cotton. Rather than adding color, this provides a clean, neutral decoration for the fixture, allowing light to glow in warm yellow tones.
