Could someone please explain how to use snaps? I have not bought any, just looked at them in the stores. I expected there would be two pieces that snap together, one on top of the paper, the other on the underside of the paper, just like regular snaps. However, when I look in the boxes of snaps at the stores there is only one piece to the snap. It looks like an eyelet. I can see nothing that would snap onto the bottom side.
How do these darn things work? TIA.
