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 of the valve and inflate 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 more air into the balloon to remove any creases.
You can now hang the balloon. You can thread the included elastic bands through the hook to secure it to a nail, for example. Alternatively, you can use a string to tie the balloon to something.
If you want to connect multiple balloon garlands, you can do so using the included elastic bands by wrapping one elastic band around two balls, one from each set. Alternatively, you can connect two balloon garlands together by tying the mounting hooks on the back with a piece of string or zip-tie.
Is the party over and you want to take down the balloon garland(s)? Carefully separate each set and open the double valve. This will allow the balloon garland to deflate faster. Store the garlands for another party!
