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.
"DIY Make your own life-size cardboard letters/numbers. Great for weddings, anniversaries, birthdays, graduations! saving this one for just in case. =)"~ I like how the pinned wrote "life-size" cuz numbers are giant in real life.
