Step 4 - Center a cardboard cake round on top of tier. Using the tip of a sharp knife, trace around edge of round; remove round. Cut 6 plastic straws equal to the height of the tier. Insert straws inside the perimeter of the marked circle, spacing evenly.

Step 5 - To "crumb coat" the cake, spread a very thin layer of frosting around sides and on top of the cake; chill. This seals in the crumbs, making it easier to spread the remaining frosting smoothly on the cake.

Step 6 - Center the cake tiers one on top of the other. Decorate the cake with remaining frosting, and pipe frosting around bottom layers to make an attractive border.
