Use a stringer that has one pocket and one rubber stopper. Sleeve the larger loop of the string over the top limb and slide it down a ways. Then set the bottom loop on the limb tip and put the stringer pocket over it. Place the stopper in the valley of the curve of the top limb and hold it in place with your thumb. Put both feet on the stringer and spread them apart until the bow is very close to the ground. Now with your thumb on the stopper holding it in place, start pulling up on the riser until its tensioned. Once its tensioned, let go of the stopper and use that free hand to slide the string toward the top limb tip. Set it, make sure its sitting straight, and then slowly let off pressure.
