Balloon arches are popular for Baby Showers, Gender Reveal Parties, and Birthday Parties. And they have made a recent appearance at many Drive-By Baby Showers and Drive-By Gender Reveals. For good reason too, as a balloon arch is a perfect way to make a pretty statement. It is one of our favorite birthday traditions in our house!

For the longest time, I didn’t believe that making a balloon arch was a project you could DIY and I wondered how to make a balloon arch! So needless to say when I found out I could make a balloon arch all on my own, I started doing it for every event I could think of!

So we put together some instructions for anyone else who wants to find out how to make a balloon arch or balloon garland the easy way! Or check out our video tutorial above.

How to make a DIY Balloon Arch

1. Plan your DIY Balloon Arch Design

Now there are a few different ways you can create a balloon arch. First off, decide is what shape you want your arch to be. Depending on the location of the arch, you will want to work out what shapes fits best in your space.

You can go for a traditional arch shape like this.

Or more of an upside down L shaped design like this.

Alternatively you can create more of a side shaped arch like this one. Ultimately, don’t worry too much about the final shape as you can adjust the shaping as you go. Just make sure you have a rough idea of how you want it to look. Plus this will help down the line with positioning of your hooks.

TIP… Make sure your balloon arch goes around the edge of a structure like a chair, backdrop frame or wall.

Once you have decided upon your shape, have a think about your color palette. Similar tones work well for a more muted and subtle effect. Or choose contrasting colors for a bolder, more vibrant vibe.

TIP… you will want to tie in the color scheme of your arch with the rest of your party decor.

Adding extra touches like leaves, florals or bows also give a really pretty and professional finish.

I like to do a very rough sketch so I have a visual to go by of the loose shape (it doesn’t always turn out exact but hey that’s OK!).

TIP… add extra touches like faux leaves and florals to add to the prettiness.

2. Go shopping!

Next, go shopping for all your supplies! Use our shopping list feature on Amazon to find everything you need in one place.

These are the things you’ll need :

  • Balloons. You will need at least 100 balloons for a small balloon arch. Go for 150 balloons for a fuller, larger display. These pastel ones from Amazon work great for a pastel color scheme. 
  • Balloon Pump. An electric balloon pump will save you heaps of time and energy! This is the one we use.
  • Fishing line or string. This Fishing Line is strong and transparent so hides nicely among the balloons. This way the balloons look like they are floating rather than strung up.
  • Hooks to attach to wall (or wherever you are positioning your Balloon Arch).

3. Blow up the balloons!

Next, you want to blow up all of the balloons.

Remember to make sure you create a variety of sizes to be able to fill in any blank spaces. So blow some full, some half full, some tiny, make sure they are all different sizes to add interest to your balloon garland! 

TIP… different sized balloons will add to the interest of your balloon arch.

How to put a Balloon Arch together…

4. Start to assemble!

Now take your blunt sewing needle and fishing line with a knot on the end.

Simply begin to thread your needle through the extra balloon material under the knot.

Now slide each balloon to the end of the fishing line, rotating balloon color, size, and direction. Squash the up as much as possible to get a fuller arch.

Put about two thirds of your balloons onto the line, and save the rest for the next step. I like to save the smaller balloons for the next part.

TIP… remember to save your smaller balloons for the next step.

5. Finish it off!

When you have put two thirds of your balloons on the line, cut and tie off the fishing line.

Of course, double-check that your shape and fullness are where you want them to be before you cut. And don’t worry if it looks a bit bare, we will be adding to the fullness in a minute!

6. Hang your hooks!

Next, hang hooks on the walls or structure where you want the arch to go. I personally love the 3M Command hooks so that they are easily removed without damaging your walls.

7. Fill in the blanks!

Now, this is the fun bit where you get to add all of the finishing touches and your design comes together beautifully!

Very carefully, using your LOW TEMP (very important) glue gun, hover over spots that need to be filled with your remaining small balloons. Or use Sticky Glue Dots instead, both work well.

Now add just a bit of glue without touching the metal tip onto your balloons. And attach small balloons to larger ones to give your arch a nice full look!

8. Hang it up!

Finally, place your fishing line over the hooks wherever desired!

These arches make a fantastic backdrop and decoration at a party! A balloon arch behind a dessert table or gift table looks amazing.

Lastly, add any floral accessories, leaves or bows that you are planning to add to give a really professional finish. If you want to add faux flowers, greenery, shimmery pieces, streamer paper, or any extra embelishments, do it after it is hung to make sure it ends where you want it!

How to make a Balloon Arch FAQ

How Early Can You Make A Balloon Arch?

Helium-filled balloons are at their peak for around 12 hours after inflating, so if you are making a helium balloon arch then try to make it as close to the event as possible.

However, if you are using air-filled balloons, they last well for days so you can easily pre-prepare your air-filled balloon arch several days before your event.

That way you get to enjoy it for longer too and don’t have to make it on the day of the party

Do you need to use helium balloons for a Balloon Arch?

No you don’t need to use helium balloons for a diy balloon arch as the balloons are all secured in place and don’t need to float.
