You want your dinner guests to be transformed into the holiday season mood immediately upon entering the dining room. A Christmas wreath laid in the center of the table can be the beginning of a perfect centerpiece. It can be decorated with any object you may want to use as a theme.
If you have no theme in mind other than something special, then ribbons and bows can always come to the rescue. Inside the wreath, place a large candle or several tapers. The tapers can be the same height or differing heights. The choice is yours. Just make certain that the flames or hot wax do not come in contact with anything that could cause a fire. I was at a dinner party once where that happened. We certainly had a lively Christmas party that night
