Tendrils of romantic buttercream wisteria adorn this majestic cake; royal-icing blossoms dangle from the natural, curly willow arbor framing the bride-and-groom topper. This vintage cake topper is from a personal collection. The columns are hidden beneath winding royal-icing vines. Since the top tiers are balanced on nine-inch columns, the cake should be assembled on the table at the reception site. If you prefer, you can use a 22-inch-diameter round cake board coated with thinned royal icing instead of the cake riser.
