1. Soak floral foam in water, and cut pieces to fit inside each bowl; the foam should extend 2 or 3 inches above the rim.
2. Stack bowls on top of one another, keeping them centered.
3. Attach lemons and kumquats to wooden skewers. Insert them into the floral foam, then fill in the gaps with flowers until the blocks are covered. Refrigerate overnight.
