Framed and unframed both look great .

This first group is not framed. You can buy Mirror clips to mount the glass to the wall

This group has thin metal frames, from Hobby Lobby. For the first ones we framed, I measured the glass and had them make the frames from my measurements. When we wanted to have a few more framed, I took the slot glass to Hobby Lobby and they measured it and made the frames. I didn't have Hobby Lobby do the framing...I did it myself.
