You can also buy custom cut peices of UV glass from Michael's or other frame shops without having to send away or pay for shipping.
What ive done is buy a small cheaper non-custom frame that has enough depth for a card and then buy the small peice of glass (Michael's employee actually cut it from a scrap and gave it to me for free since it was so small).
I hung mine but it would look even better on a shelf probably.
