Instructions: 1. Locate a vacant corner (two walls and floor) in the designated space. 2. Place the plywood board on the floor. 3. Paint its exposed surface black. 4. With the axe, remove a narrow strip of wood from the elongated part of the board. 5. Turn the two parts (the main part + the strip) so that the painted surface will be face down, and attach it to the corner. The narrow strip will be located in the inner part of the corner, between the walls and the floor. 6. Now lift the narrow strip at a 90-degree angle, and attach it to the corner of the room.
