Jess (falconry) the bird, but the width is proportional to leg-length. Traditional jesses are made from a single length of leather, and slits are placed strategically along the jess to allow it to be looped through itself and around the ankle of the bird so that it fits comfortably but securely about and just above what would be the bird's ankle. With Aylmeri jesses, as created by Major Guy Aylmeri, the end of the jess is instead looped through itself repeatedly to form a "button", or knob at one end. The thin, pliable end of the jess is then threaded through an
Falconry training and technique to stay supple. The anklets are grommetted on, like their leather counterparts, but instead of a folded button keeping the straps from falling through the anklets, a knot is used. The end of the knot is melted with a cigarette lighter to keep it from fraying. In order to form the loops the swivel or clips will attach to, a nylon parachute cord is hollowed out, threaded up through itself using an awl, and knotted. The swivel is to prevent tangling and twisting of the leash or tether when the bird is active but not hunting. The swivel consists of
