In another NG, they suggested panel pins. I would think I would
have to put a sheet of cardboard between for that, so I don't get a
scratched mirror over time.
For that size glass, 3/4" panel pins. Lay the pin flat on the
cardboard, push down hard and whack it with the edge of a flat sided
chisel or similar. Difficult with a hammer.

I actually have a panel pin pusher that I have only used once before, that
should do the trick.
