Cute idea for backdrop at a childrens party. Or switch the colors for a high school or college graduation party, baby or wedding shower. Secure balloons together with ribbon and make sure you create a circular effect with them.
Love this idea for table decor: Place 1 vase inside another -> fill gap with candy, etc. -> fill inner vase halfway with water -> secure flowers with rubber band -> place inside inner vase. (Those fruit loops loke disgusting but the idea is cute!
