Why not make a card with a bookmark? But, at the same time, how to make a simple card for a boy?
As you can clearly see (sorry for being corny), I used a piece of clear acetate on the front of the card, slipping the bookmark under the clear acetate. In order to keep the bookmark from sliding through, I used a piece of ScoreTape on the bottom edge of the acetate and then covered it with a piece of rick rack (matching the rick rack on the bookmark) so the tape would not show through the acetate. I secured the top edge of the acetate with eyelets.
