Lay out sheets of old newspaper to protect your work surfaces. Place one of the wooden plywood boards that is 10 inches by 6 inches on top of the newspaper, so that it is lying vertically. Use the ruler to locate and mark the middle of the board (width-ways). At the bottom of the piece of wood measure 3 inches up and mark with the pencil. From this mark, draw a line 2 inches horizontally. Now draw a line straight up from this point to the top of the wood. Repeat with the other side. You should now have a template that has a rectangular shape at the base, with a long horizontal rectangle coming up from its center.
Use the saw to carefully cut along the pencil lines to create your wooden template. Sand down the outer edges of the wood with the sandpaper so that it is smooth. Measure and mark the spot that is 1 inch in from the top length of the rectangular base. Saw a cut into this mark that is 1 inch deep. This cut will be used to hold the other wooden planks that will stabilize the clothes rack.
Repeat Steps 1 and 2 with the other piece of 10-by-6 plywood board.
Hold one of the cut plywood pieces vertically and slot the two 2-by-12 boards into each of the 1-inch cuts. Slot the other ends into the cuts in the other cut plywood board.
Squeeze a drop of glue directly onto both ends of the dowel rod. Insert the dowel rod between the two plywood cut boards roughly 1-inch below the top edge. Apply light pressure to the outside edges of the boards and hold for several minutes until the glue sets. This will form the clothes rail.
