Q&A for How to Make a Balloon Arch

Sure you can! For this, you definitely want to buy a strong and heavy base, otherwise the wind (or the kids) can knock it over pretty easily. Other than that, the process is the same.

Maybe about 60-80 balloons?

You can get the arc online at the Oriental Trading Company, Amazon, Ebay, or a party supply from your area.

If you mean tying the balloon itself, start by blowing it up. When it's finished, carefully stretch the very end of the balloon until the rubber is about one to two inches long. Use your fingers to tie that piece of rubber into a knot, which will then hold the balloon closed. If you're asking how to do tie the balloons to the arch, you could just use tape.

An arch will hold for 3-4 days, then it will begin to deflate (this is an arch using air not helium). They take all day to make, so it is a good idea to do it ahead of time if you can.

Probably not. A thin wire will probably bend under the weight, but if you used a thick coil or stick, that would work.

You can tie the tails of the balloons together or use string or ribbon.

It depends on the length of the arch. It also depends on the area at the bottom where we hold the balloon.

Generally, latex balloons are best for balloon arches, but any will work. Balloons filled with helium are best for indoor events that last a few hours, while ones filled with air are best for events that are held outdoors.

A couple of days, depending on how fast you work. You could get a medium sized ( around 1.5 meter to 3 meter ) long balloon arch done in about 2 afternoons of hard work. If you have helpers though, you can make one much faster.
