1, use scissors to cut two small holes near the edge of the prepared small piece of leather, and directly put one end of the long rubber band through it.
2. The rubber band passing through the small hole is slightly elongated and folded in half, about 1 cm long.
3. Take a short rubber band and tie the long rubber band folded in half to the left and right. When tying, the hand holding the folded rubber band can exert a little force, and the binding effect will become tighter.
4. After winding three or four times from left to right, pinch the small leather and the folded rubber band with double index fingers and start knotting and fixing.
5. Knotting a knot must be very important. You can shorten the rubber band with a little force, because the rubber band is elastic and not easy to break, and the tied knot is not easy to loosen.
6. This method of tying rubber bands is effective and targeted, and the rubber bands will not shift and will not rebound after the marbles are launched. I won't hit anyone, and I won't hit the bow door.
