Home Wedding Day Pins Seascape Centerpieces Dress tables with sculptural shells and coral-like pieces. Large conch and murex shells with cattleya orchids nestled in their openings and smaller marlin spike shells surround a vase filled with tiny shells and a pillar candle. Painted manzanita branches stand in for real coral. Capiz shells (sold with predrilled holes) are tied to napkins with ribbon — a small branch rests on top.
