50 Paper Circles with hole in the center - from old book pages

These paper circles have a HOLE in the center. They are punched from book pages. In the center there is a pre-punched hole, that comes out easy with something like a toothpick.

Diameter: small 2,2 cm (7/8")

See foto, what I am creating out of these circles. But I am sure, that you have also other ideas, what to make out these, crafting, mixed media artwork, scrapbooking, paper garlands,....
