1. Build a balloon arch frame using the instructions inside the balloon arch kit.

2. Air-inflate balloons and tie 4 together.

3. Position your first layer at the bottom of one side of the arch.

4. Insert balloon lips into balloon disk holes.

5. Add layers using the same technique to complete arch.

Balloon arches need between 90 to 140 11-inch balloons to create. This greatly depends on the sizes of the balloons, clustered versus single line balloons, and the desired overall height and width of the balloon arch as this can impact how many balloons you need per foot.

Balloon arches typically last between 8 to 12 hours for arches that use latex balloons, properly filled with helium without Hi-Float treatment. However, not all balloon arches require helium. How long a balloon arch will last can also depend on environmental conditions and the use of mylar and foil versus latex.

Balloon arches don't need helium since they can also be filled with air. While helium will help give support and structure to a balloon arch, filling balloons with air also works well if the arch uses a strong yet flexible material, such as PVC pipe or aluminum rods, with a stable anchor on both sides.

A balloon arch can take anywhere between 30 minutes to 2 hours to create. The time to construct a balloon arch depends on how complex the arch design is, how many balloons are being used, how many hands are working on the balloon arch at the same time, your experience level, and how you plan to fill the balloons.
