Matting?

[workinggirl-ctv.livejournal.com]

I have a few of these:




I cut pieces of vintage books to fit each frame. I coated them with Judikins MicroGlaze to improve durability, but I have a problem. Everyone wants to open the pendants! When they do, my little bits of paper come floating out. Also, some of the frames don't close tightly enough and the papers slip around a little.

I really prefer to make a nice sturdy product. I think I need to adhere the paper to something, maybe matting like is used when framing pictures? I need something with a little thickness and a little give...

I'm also wondering if I'll be able to glue or tape any of the ones I've already MicroGlazed.

Ideas? Input?
