1, thread. Hold the 8-shaped ring with the left hand, and thread the thread end of the main line into the 8-shaped ring hole with the right hand, and thread it back and forth for three times to form a double ring with a diameter of about one centimeter.
2. Turn around. Hold the double loop in your right hand, wrap it around the main thread once or twice (the more loops, the stronger the knot), and then lead the head of the main thread out of the double loop.
Step 3 tie a knot. Hold the main thread with your left hand, pull the main thread with your right hand, tie the knot hard, and then cut off the extra thread.
