A coat hanger is another simple thing to make - provided you go at it in the right way. A paper pattern should first be made, and for this we will need a piece of smooth wrapping paper large enough for us to mark out three rows of one-inch squares, fifteen squares to the row. Tack this down and then tie a piece of string to a lead pencil in order to draw the two curves, which is a very easy matter when the other end of the string is tied or looped around a tack. For the top curve the string should be thirteen inches long and nineteen for the lower. In order to place the curves properly on the squares, keep shifting the tack until the two ends come out just right. We must now get a piece of wood about three quarters of an inch thick and fifteen inches long, and mark out the pattern on it. The hanger is then to be carefully sawn out with the keyhole saw, after which the edges should be planed smooth and rounded off and the whole piece finally gone over with sandpaper. Next bore a small hole in the center at the top, and then make a hook out of good stout wire, the end of which should be pushed through the hole and bent over to keep it from coming out, after which a coat of thin shellac will complete the task.
