Sparklingly simple centerpiece. Fill with flowers, small green plants in flat containers, multicolored poms, blinged out styrofoam balls...just about anything.
Prevent tablecloths from billowing. Gather sun-bleached oyster or clam shells, sides still attached. Slip jute, knotted at both ends, between open "wings" of the shells, and lay across the table. For a centerpiece, gather turban shells and scallops.
