When it comes to the hearth, Martha loves to bring the outdoors in—especially fragrant greens. Display buckets of evergreen clippings from your yard around your fireplace. "These are just the tips of an evergreen tree, which needed pruning anyway, so you're not hurting anything."
To create a dramatic wall fixture, Martha says she simply covered chicken wire with moss and hung a wreath for contrast.
For Santa's stockings, Martha recommends hanging clips underneath the opening of your fireplace. "You don't hurt the good wood," she says. "You'll never see a tiny hole, and if you worry, you just fill the hole with a little bit of wax after you take the things off."
And put away the tchotchkes! Instead, line your mantle with moss nestled with pieces of fruit (Martha uses pomegranates) for a fresh, uncluttered look.
