Let guests' well-wishes take flight on paper doves. These birds are traditional symbols of love, happiness, and harmony. Anchor bare branches (these are manzanita) in a large, sturdy vessel filled with stones or gravel. Use wire to secure nests, available from craft stores, to branches. Set dove cards -- available precut -- in a dish. Place pencils alongside your tree with a sign asking guests to inscribe a card and to place it in a nest.
