How to Style a 2-Color Arch

The mistake most people make with school colors is creating a "Candy Cane" effect (perfect stripes). For a modern, professional look, you want Color Blocking.

The "Organic" Method:

  • Cluster, Don't Stripe: Group 4-5 balloons of the same color together, then switch. This creates big "clouds" of color rather than thin stripes.
  • Use Mini Balloons: The calculator includes 5-inch balloons. Use these to fill gaps after the main arch is hung. They hide the mechanics and add depth.
  • Add Props: For graduation, it's popular to add "2026" foil balloons or a "Congrats Grad" banner into the arch itself.
