I found this fun invitation from Somewhat Simple that would be great for inviting couples to a dinner party. She shows how she used the can for a little girl Princess party. But imagine the possibilities with an adult party! For a Mexican themed party you could fill the can with squares colorful confetti and a little maraca. For an Italian themed party you could fill it with colorful Italian pasta. For an Asian dinner party you could put some fortune cookies. I could go on and on. Not to mention what cute table decorations these would make and then send them home with each couple or guest as a party favor!
