Jump rings are formed with a single circle or oval that is cut so that it can be opened. NEVER open a jump ring by pulling the two open ends directly away from each other, always slightly twist the arms to open. Twist one arm backward and one forward, so you create an opening without compromising the round shape. Pulling the ends apart will cause the ring shape to be distorted and hard to get back together.
Close in the same manner and make sure there is not a gap between ends, if there is, open and close again aligning ends so they touch when closed.
