Inflate balloon with helium. (Tip: A helium tank is easy to use when inflating latex balloons. To use, slide a balloon onto the nozzle — specially designed to grip the balloon by the neck — fill to desired size, remove, and tie off.)
Measure and cut a swatch of tulle for balloon.
Cut a length of ribbon. Wrap tulle around balloon, gathering neatly at the base, and secure using ribbon.
Optional: Heavy tulle may weigh down the balloons, even when filled with helium. To give them the illusion of floating, monofilament may be strung from an above fixture or a balloon pole may be used.
