Throwing a New Years Eve dinner party is your chance to really go over the top with decorations.
Play with it and have fun – maybe think of a theme or subject your guests will appreciate.

More colors are usually more confusing to the eye than more shapes.
Other than that: no rules!
I have browsed the net for inspiration on how to decorate my own table for the last day of the year and these favorites I would like to share with you (click on images for larger view):
