A mold is made for molding artificial quoins. The mold is made from plastic structural sections in two main pieces which may be interengaged together by means of a straight and hooked detent cooperating together with the hook on the opposite side on adjacent interengaged arms to provide more security. The mold forms quoin facsimiles upon the surface of the buildings to imitate quoin blocks on such corners.
