Mount a shelf to the wall (min 1 1/4" thick).
How does it hang? No one can tell!
Screw anchors are placed in the wall in 6mm (15/64") holes and the mounting bracket is affixed to them. The support rod is fixed to the mounting bracket with set screws (vertically and horizontally adjustable). 12mm diameter x 3 5/8" deep holes are drilled into the rear of the shelf to seat the rod. For added invisibility, a 7/8" wide groove by 3/16" deep may be cut into the shelf back for full concealment.
