Here is my scrap plywood, you can see how the edge isn’t straight
I laid the mirrors down first to see how many would fit and then measured where I wanted it to stop
Then cut off the extra pointed edge
I painted it with acrylic paint
Then I laid the mirrors out again and glued them into place.
On the back I added 2×12 cut down to the size I needed to create a frame.
I hung saw tooth thingy’s onto the back and I’m using drywall anchors to hang it in the room.
