Cute idea for backdrop at a children's party. Or switch the colors for a high school or college graduation party, baby or wedding shower. Could have a lot of fun. Secure balloons together with ribbon and make sure you create a circular effect with them.
I MUST do this with my girlfriends - so much fun! A Favorite Things Party -- Love this idea! Each guest brings their favorite item (5 of the same thing) costing around $6 and a favorite treat or dish to share with everyone!. Girlfriend Christmas party this year. Fun stuff!
