How to build it

  1. Cut the shelf to 24″ and the cleat to 22″.
  2. Find the studs. A 24″ shelf spans at least two studs at 16″ centres, so screw the cleat into both. Check it with a level before the second screw.
  3. Set the shelf on the cleat and mark where the cleat meets its underside.
  4. Drive screws down through the shelf into the cleat, countersinking them so they can be filled.
  5. Fill the screw holes, sand flush, and finish.
