I use large cream paper napkins rolled up with a gold bow tied around (meant for decorating christmas trees) to coordinate with my cream tablecloth

If you are going to use flowers for a centerpiece, make sure they aren't strong smelling! Or even better, use flowers with no smell.

If flower arranging scares then just fill a crystal bowl with water, add some red colouring and then add floating candles and flower heads. Looks wonderful.
