Trim the dome tops of the cake to make sure each layer is flat and stable.
Ensure proper support by placing each tiere on a sturdy cake board that is the same size as the cake.
Insert dowels in the bottom tiers to support the weight of the upper tiers and keep the cake from collapsing.
Refrigerate each cake tier to make the texture firm so the cake holds the shape.
Ensure precise alignment by measuring and marking the centre of each tier and cake board.
