Hold the mirror against the wall at the desired position.
How to hang a large frameless mirror on a wall.
Place 2 clips on the bottom 1 on each side and 1 on top for most mirrors though a large mirror may need more.
To use clips put the mirror where you want to hang it and use a pencil to mark the top and bottom corners.
Mark the location of the top edge and the center of the frame.
D rings and picture wire the mirror must have a frame around it to hang a mirror this way.
Remove the mirror and put another mark two inches below the first mark.
Screw one end of the cable to the wall anchor.
Place a scrap piece of wood that is approximately half as long as the mirror is wide underneath the hanging wire on back of the frame.
Jiggle and slide the top two clips down over the top edge of the mirror securing it against the wall.
Screw your wall anchor into the second mark you made.
Take the mirror out and hold it up against the wall in the position you want it to adorn.
Keep one hand pressing the mirror against the wall.
Reposition the mirror to its original location and screw the other end of the cable to the top of it.
Make a mark where you want the mirror to be.
Use a screwdriver or drill to tighten the top two clips so they are no longer loose.
This requires attaching d rings to the back perimeter of the mirror frame wrapping wire around the d ring and then attaching one or two hooks to the wall and hanging the mirror by the wire.
It would be easier to go through this step if you have someone to help you on the side.
Grab a pencil or a marker and take note of the bottom and top corners of the mirror.
You can now place the mirror back in its place.
