Chandelier: Oprah's chandelier is draped with a boxwood garland. Other ideas: Tie on ornaments with ribbons, or drape the chandelier with garlands of faceted glass. (Crystal garlands are available at Potterybarn.com.)
Fireplace: Arrange a basket of pinecones and greenery next to the hearth. (For a box of evergreen and ponderosa pinecones, see Williams-sonoma.com.)
Mirrors: Wrap tiny white tree lights around the frame of a large mirror or decorate with a swag of spruce and red berries.
Hall: Attach pine or eucalyptus garlands over an entryway, or tie branches of greens and tiny tree lights together with ribbons and silver bells and twist around the banister. (Find pine garlands at Jcpenney.com.)
Tree: For a traditional tree like Oprah's, choose ornaments with an antique look and mini amber-colored lights that cast a warm glow. (A range of vintage-style blown-glass ornaments is available at Midwestofcannonfalls.com; tree lights at Frontgate.com.) Start a collection: Throw a tree-trimming party, and ask guests to bring an ornament. (For information on how to order a fresh-cut tree from a tree farm or to find growers near you, try Christmas-tree.org.)
