How to tie a T-knot?

Process: 1 The main line is bent into a ring, and one end of the sub-line passes through the bottom. Pinch the joint of the two lines with your thumb and forefinger, start winding the ring with the secondary line, pass through the top 3 of the ring, grab both ends of the secondary line and the main line, and tie the knot. After this knot is tied, don't worry about it. Next, the two main lines are overlapped into a circle with the main line 5 and wound around each other for 6 times. 6 Pass your finger through a small ring in the middle and the first knot.
