This grand stack of 5 rectangular tiers was inspired by vintage chenille bedspreads. Each tier is coated with Swiss Meringue Buttercream, then covered with Crisp Meringue Panels of Swiss Meringue.
Cut foam board into rectangles, one each in these sizes: 18 by 16 inches, 15 by 13 inches, 12 by 10 inches, 9 by 7 inches, and 6 by 4 inches. Place tiers on the corresponding- size foam-board rectangle, and fill and frost tiers with the buttercream.
Insert 3 dowels down the center of the 18-by-16-inch tier, one in the center and the outer two 2 1/2 inches from ends of cake. Insert 6 more dowels, one on each side of each center dowel, 2 1/2 inches from the side edges of cake. Insert 9 dowels in a similar manner into the 15-by-13-inch tier. For the 12-by-10-inch tier, insert one dowel into the center, and place 4 more, one at each corner, 2 1/2 inches from the edges. Insert 5 dowels in the 9-by-7-inch tier in the same manner.
At assembly time, center the largest tier on the wooden base. Carefully stack the tiers on top of one another, centering them. Store the cake in the refrigerator until just before displaying it.,
