Prepare floral container by filling it with a piece of foam. Push a single candle down into the center of the foam if desired. If the container is oblong you can use three candles, staggering the heights.
Fill in the outer edges of the container and foam with evergreen twigs. You can mix pine with fir if it is available or use leather leaf and cedar from the florist. The greens can cover the container and flow down onto the work surface.
Place filler flowers throughout the greens. Keep them low and away from the candle. Cut flower stems down to six inches or less. Place them into the foam.
Continue adding flowers in a circular or oblong shape according to the area that the centerpiece will fit in on the dining table or buffet table.
Add in natural cones, nuts, ornaments, a ribbon bow, faux candy canes or any Christmas decoration that appeals to you and matches the table decor.
