To make your sling, cut two lengths of cord, each 2½-feet long. Paracord is fine, but you could use almost anything. Tie a bowline knot in the end of one line, with a loop big enough to slip over your thumb. Tie three or four knots at the end of the other line. Figure eights or overhand knots will suffice. Cut a football-shaped piece of cloth or leather about six inches long and three inches wide. This will be your sling pad. Pierce a hole at either end of you sling pad, where you will attach the unknotted ends of your two lines. Use good, tight knots so your sling doesn’t fly apart while in use. Two half hitches with a stopper knot is a good choice, or at least an overhand with a stopper knot as pictured.
