How to adjust the slingshot rubber band

First of all, when cutting, measure the size, use a plastic ruler as a standard, and straighten the rubber band evenly along the ruler to let the rubber band stretch naturally. Generally, the length of a rubber band should be 26-28 cm, and the length of two rubber bands should be the same, so that a single rubber band is folded in half at the bisector, passes through two holes in the leather bag, and then is tied tightly with thread and the like, and the rubber band head is cut neatly with scissors. Generally, the length of the tied rubber band should be 12.5-.
