Unfold the balloon and, if possible, let it warm up in the sun for a while.

Inflate the balloon (preferably with a pump). If some air escapes when closing the valve, open the first cap and blow some more air into the balloon. The double valve prevents air from escaping but allows air to enter.

Let the balloon rest for a moment and then blow some extra air into it to remove all creases.

You can now hang the balloon. You can thread the supplied elastic bands through the hook to hang it on a nail, for example. Alternatively, you can tie the balloon to something with a string.

If you wish to connect multiple balloon garlands, you can do so with the supplied elastic bands by wrapping one elastic band around two balloons (one from each set). Another option is to connect two balloon garlands by tying the mounting hooks on the back together with a string or cable tie.

Once the party is over and you wish to dismantle the balloon garland(s), carefully detach all sets from each other and open the double valve. This will deflate the balloon garland most quickly. Store the garlands for your next party!
