All Boxed Up -- A rustic wooden toolbox lets a holiday centerpiece spread out. Stand pillar candles on supports, such as candleholders or even soup cans, so they are set at different heights. Next, add bowls or low containers of damp florist's foam and arrange the greenery. A sweep of garland and a cardinal's nest add a final touch. Editor's Tip: Be sure to keep the candle flames a safe distance from the greenery and other elements.
