Ice Cream Sundae Bar - my mom did this at me and my 3 siblings& communion parties, it was a blast! Can& wait to do this when I have kids& parties (although my adult friends have certainly enjoyed when I do it for them lol)
The design is for a birthday invitation, but it's a great idea for a launch party invitation! Encourage your guests to bring their balloons. They can double as a party game if you put little messages inside of them!
