How to use eyelets:

Decide on where you want the eyelet to be on your card and mark with a pencil. Using the hole punch tool, make a hole in the card.

Insert the eyelet in the hole and turn your card over.

You will now notice that the eyelet is raised above the card (this is because the eyelet still needs to be set).

Using the Eyelet Setter Tool and a small hammer, gently tap over the eyelet until it goes flat.

Your eyelet is now secure.
