Pillar & Stacked Cake Construction
Mark all tiers for dowel rod placement using a separator plate (for pillar tiers) or a cake circle (for stacked tiers) the same size as the tier above. Insert dowel rods. The key to success is inserting dowel rods accurately at every level for support.
Position the tier which will be on pillars on a plate 2 in. larger in diameter. The two separator plates which will connect the pillars should be the same diameter.
Starting at the bottom level, stack tiers.
Position the separator plate (feet up) that will support the tier on pillars.
Position pillars over feet.
Carefully position the plated tier on the pillars.
