You can hand out themed pins or goofy hats to your guests as they arrive or as prizes. These help to add a decorative party atmosphere. Then get set to do a whole lot of giggling for the next few hours as your guests get into party mode.
Anything with a smile is a great prize to hand out for your smile party games but one of my favorites for this type of party is Jellybelly beans. They add an extra touch of humor to the games when only one jelly bean is given out for each win.
Jellybelly Beans come in a variety of colors and extremely unusual flavors so be sure to make quite a show out of the flavor that each guest receives as their winning prize. The giving of this small treat takes the stress of winning off your guests but it is also a prize that will be highly desired by your participants.
The surprise of which flavor is to be handed out next, adds to the excitement and it is amazing how much laughter this prize adds to the event.
Theme your party around Smiles and have plenty of these images on hand. Stickers, balloons, plates, and hats.
