Add your finishing touches. Use a hole-punch to create a hole at the top of your bookmark. Cut a piece of ribbon to be 6-8 inches long, and fold it in half. Then place the loop-end of the ribbon through the hole punch and slide the tail ends through the loop, pulling tightly.
Add multiple ribbons for more color and texture on your bookmark.
Use beads on the ends of your ribbon for a bit of glam. Slide a few beads over the ends of both the ribbon tails, and then tie a knot to secure it.
Use a match or a lighter to burn the cut-ends of the ribbons to prevent fraying. The flame will cause the plastic to melt, creating a blunted-end to your ribbons.
