Each arrow should be roughly half the length of the bow, or as far back as the bow can pull. It is ineffective to have arrows that cannot be drawn back to the bow's capacity. Consider the following elements as well: Green wood can be used provided you let it to dry out naturally, as the sap may ignite if dried over a fire. Iron arrows can be recycled, but only once. Arrows are made of three parts: the head, the shaft and the fletchings. The head is the actual projectile that will find its way into your target. It can be as simple as a stone or as complicated as a metal point with vanes. The shaft is the part that connects the head to the fletchings. It can be of any material as long as it isn't too brittle. A strong arrow will need a thick shaft to provide sufficient mass. Fibers from plants are used to make string for shooting arrows. This includes sinew, which is the inner core of a deer's tendon or muscle tissue, and hemp or jute, which are types of cannabis plant fiber. Stringing an arrow is easy. First, determine how many feet of string you will need by multiplying the distance between your archer's elbow and knee by four (for safety). Next, divide this number by the number of strings you will use. For example, if you plan to use five strings, then your string length should be eight feet.
