These mason jars could double as centerpieces and favors. Place enough in the center of each table for each guest to take their own. You could make them in different colors and fill them with candles or candy or flowers.
Cool way to serve the plasticware and napkins at a birthday party! Get them in a color to go with the theme of the party. Wrap the the napkin around the plasticware, then tie it with some yarn. Hot glue an owl, princess, star, etc to the yarn to go with the theme of the party!
