Unfold the balloon and let it warm up in the sun if possible.
Inflate the balloon (preferably with a pump). If some air escapes when closing the valve, open the first cap of the valve and inflate the balloon with some more air. The double valve prevents air from escaping but allows air to enter.
Let the balloon rest for a while and then inflate it with some extra air so that all creases disappear.
You can now hang up the balloon. You can thread the supplied elastic bands through the hook, for example, to hang it on a nail. An alternative is to connect 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 placing 1 elastic band around 2 bulbs. 1 from each set. Another option is to connect 2 balloon garlands by tying the attachment hooks on the back together with a string or zip tie.
When the party is over and you want to deflate the balloon garland(s). Carefully detach all sets from each other and open the double valve. This way, the balloon garland deflates the fastest. Store the garlands for the next party!
