I have seen the balloon arches run about $400-800 depending on the design. You can decorate your quinceanera with a few items
- Balloons $25
- Helium Small Tank $100
- Wire $3
- Box $2
Okay so I found this video online to show you how to make them, it is very easy. The most expensive will be the helium tank, but you can use the tank for other event decorations such as baby showers, birthday and any get together.
