Balloons taped to a wall to resemble by bubbles. This would be awesome at a bridal shower or another kind of party with a champagne bar. Love this idea! Use pearlescent colors for an adult party and primary colors for a kids' party.
Party Prop: Start with a hula-hoop and several rolls of crepe paper. After attaching one end of each crepe paper roll to the hula-hoop, raise the hula-hoop into place. Twirl crepe paper and attach ends to walls.
