For a contemporary centerpiece that turns into party favors at the stroke of midnight, arrange a group of colorful noisemakers on top of a cake stand (use glasses to hold any items that don't stand up by themselves). Fill in the surrounding spaces with tinsel. When it's time for the countdown, every one of your guests will have the means to make plenty of celebratory noise.
All it takes is a rubber stamp and an ink pad to customize stationery-store staples for a New Year's celebration. Crafts stores sell number stamps in many styles and sizes, as well as ink pads with special ink that can be used on almost any surface. Decorate balloons, paper napkins, hats, and other items. Let dry overnight.
