Position the tier which will be on pillars on a plate 2 in. larger in diameter. The two separator plates which 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.
