Cookie Monster Balloon Arch: the premise of building any balloon arch is generally the same, no matter the theme. For my comprehensive guide to ALL balloon garland basics, check out how to DIY a balloon garland (from a balloon professional).
Having said that, sometimes it’s just hard to get started. Whether the issue is picking out colors, organizing the garland, or general setup questions… I can help you as a former balloon artist!

How to get started building your arch:
The first step I like to complete when making any balloon garland is organizing all the uninflated balloons.
I organized based on the following:
- size
- color
- extras
From there, I build the base!
The base of my balloon garlands is usually built with quads of 10″ or 12″ latex balloons. Before starting this process, it’s important to know whether you’re color-blocking the balloons or variegating the garland. If you’re color-blocking, then you’ll build quads out of each color without mixing them up. If you’re variegating, then you’ll of course mix the colors. Mixing is sometimes hard for people who are OCD (like me) and want to turn balloons into math. My favorite phrase to tell employees when I owned BomBoms is that “balloons are abstract”… it helps when the math doesn’t quite math and you have to just do your best. 🙂
Once you’ve created your quads, I like to add all of my BIG balloons.
I try to add 1-2 24″ balloons every 3 feet. This makes the garland really wide, really full, and immediately makes the garland so much longer if you’re aiming for length. Keep in mind- if you’re making a balloon column or a hula hoop happy you’ll probably stick this step as those are made for easy travel in a car and installation.
After that, I like to add 5 inch balloons. I like to link two quads of 5 inch balloons and insert those every 2-3 feet.
Finishing touches:
Once you’ve hung the garland in it’s desired location, I recommend adding foil or mylar specialty balloons last. You can tie them in using the tongues, using ribbon or fishing line and the small holes available or you can use glue dots. It really depends on the location you’re hanging the garland in whether you’ll want to use glue dots or not. I don’t recommend glue dots for windy or outdoor installations, personally.
