If sugar-free is more your style, feel free to use plain fruit—and get Martha's tip for making your display sky-high. Take footed glass pedestals (or cake stands) of varying sizes, and stack them on top of one another. Place two small pieces of floral tape on the bottom of each stacked piece to ensure they won't move.
Once your base is set, stack an assortment of fruit, pinecones, leaves or nuts to create this edible centerpiece. "If you wish, dress it up with little ribbons coming down it," Martha says.
