1. Pick a braided rope you like. Here, choose a yellow Chinese knot braided rope, hold the rope end with your left hand and wind the rope counterclockwise with your right hand.
2. Then, the right end of the line is wound counterclockwise for half a turn to form two overlapping circles, and the left hand grasps the left intersection.
3. Press the left end of the right line counterclockwise, press the lower right circle, pick the left line, press the right line, and pick the upper left circle to go out.
4. The tail of the right line is counterclockwise downward, the left line is pressed on the right new circle, and the left and right intersection lines are picked up and passed through the central square position.
5. The index finger extends into the central square position, and the woven Chinese knot wraps around the left line to form a ring around the index finger.
6. Pull out your fingers and stretch the left and right ends with both hands.
7. Adjust the tightness of Chinese knots to complete the knitting of single-thread buttonholes.
