Lay a 15-inch board flat. Draw a line across the board parallel with the 15-inch edge, and two inches away from the edge. Draw another line across the board that is parallel with the first, and two inches away from the opposite 15-inch edge. Repeat this process on the other board.
Position your board so the lines are vertical. Draw an "X" over the left line two inches down from the top of the line. Draw another "X" on the same line nine inches below the first. Rotate the board 180-degrees and repeat this process on the other line. Repeat this step with the other board.
Drill a 3/32-inch pilot hole through the markings and through the board. Drill a ½-inch deep, ¾-inch diameter hole into each of the pilot holes. All of the ¾-inch-diameter holes should be on the same side of the boards. Turn the boards over and drill a ¼-inch deep counter-sink hole into the other ends of the pilot holes. Erase the pencil markings.
Position the boards on their 8-inch ends, parallel, so the ¾-inch holes are facing each other and aligned. Place a dab of glue that is about the size of a dime inside each of the holes. Place the ends of the dowels inside the holes, and screw through the boards and into the dowels. The screw heads should be inside the counter-sunk holes. Wipe any excess glue of with your damp cloth.
Sand down the shoe rack with your medium-grade, and fine-grade sand paper. Wipe the rack down with a tack cloth and apply your wood stain. Let the stain dry according to manufacturer's instructions.
