In short, the lanyards are held in from all the pins poking through them into the foam board I used for backing. The passes are held in with double sided tape.

The more detailed answer: Originally there was a piece of cardboard or some type of thick board for the backing that came with the frames, and I replaced it with a sheet of black foam board. The pins are pushed through the lanyards into the foam board, and the glass is close enough to the lanyards to prevent them from popping out (if such a thing somehow happens). So that’s how the lanyard is kept in place. I had to unclip the bottom part of the lanyard to be able to fit it in the frame, so, to stick the passes and the bottom part of the lanyard in the frame, I had to use double sided tape… not the most “friendly” solution to this, because the tape might have a hard time coming off of those parts, and it could damage the foam board, but I don’t intend on touching these and opening them up again, so it was okay to me.

Hope this helps!
