Conversation-starters are the best way to get a holiday meal going. Re-invent puzzle pieces as snowflake napkin holders by gluing several pieces together, then attaching to basic rings with twine or hot glue.
Casual is best when it comes to a potluck dinner table setting. Use what you have on hand; consider white or neutral organic tableware and everyday flatware. Atop each plate, place a folded linen napkin and a small place card, nestled in a sprig of succulents. Other place card holders include flowers, ivy, a piece of chocolate, a crusty French roll, or a candy-filled egg cup.
