does anyone have a quick how-to on using the tying discs for latex balloons?
the rental place can provide the ties that are a circular disc with a hole in the middle (picture a plastic donut)... but i'm not sure how to use them.

i've googled it, but haven't found anything.




ETS:
"how to" is not the appropriate term.
i googled "tutorial" and i found exactly what i was looking for lol
