Tutorial: DIY Tissue Paper Pom-Poms this tutorial is pretty good. Use square sheets or tissue for a rounder Pom Pom. Tie the middle with ribbon and tied several on ribbon and hung them for a backdrop. Use thin tissue paper and fluff gently.
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.
