If you're serving food or drinks at your party you will need napkins. Lots of napkins. Guests need them to wipe their hands and face with after they eat, and they'll be needed to clean up the little messes and spills that are bound to happen. Even though napkins are bound to get dirty and crumbled up, there's still no reason they shouldn't match the rest of your party supplies. Party napkins come in so many solid colors that you'll have no problem picking out fun ones that compliment your party theme.
