With chain nose pliers, grasp the wire 1/4″ – 1/2″ from the end. Turn the pliers to bend the wire in a 90-degree(right) angle.
With round nose pliers, grasp the very end of the wire. Roll the pliers upward to make the loop — let go and move the pliers if necessary to form a round loop.
Use chain nose pliers to open and close the loop by turning the wire sideways as shown.
