How is tulle used in balloon decorations?

Tulle is draped or woven through balloon arches and garlands to add soft texture and fill visual gaps between balloons, and it's also used on its own for backdrops, table skirting, and bow accents.

What length of tulle roll do I need for an arch?

For a standard 6 to 8 foot balloon arch, a single roll of 25 yards is usually enough to weave through generously; larger installations or full backdrops may need 2 to 3 rolls.
