In attaching patches to window or door screens, the work requires a continual shifting from one side to the other, or two persons, one on each side, must be present to pass the threaded needle back and forth. The operation can be easily simplified by using a bent needle, which has been heated and suitably shaped. The point of this needle can always be made to return to the side from which it entered, thereby avoiding the need of an assistant or the tiresome shifting back and forth. - Contributed by G.
