Punch out the holes in your folder carefully.
Place the whites circles around every hole.
Using the eyelet guider thing, place the eyelet on top of it.
Place the folder hole over the eyelet that is on the black piece.
Add the top eyelet and place the silver piece on top so you can hammer it down.
Hammer it down!
Repeat this step for each hole. To save them, I only did three on half of the folder.
