1. Prepare required materials and tools: jade thread, scissors, tape measure and lighter.

2. Let's cut a 170cm jade line first. Then fold the line (as shown in the figure below 1). The right line is about 30 cm longer than the left line (the left line is the left line and the right line is the right line). Then wrap a buttonhole around the crease (as shown in Figures 2, 3, 4 and 5), with a buttonhole diameter of about 0.7 cm.

3. Then tie a knot: Step 1: Make a circle for the right line from right to left and wrap the left line from bottom to top (as shown in the following figure 1); Step 2: Make a circle for the left line from left to right and wrap the right line from top to bottom (as shown in Figure 2 below); Step 3: Tighten the thread (as shown in Figure 3 below).

4. Now let's weave the bird's head knot: Step 1: The right line makes a circle from right to left and winds the left line from top to bottom (as shown in the following figure 1); Step 2: Draw a circle on the right line from right to left, and wrap the left line from bottom to top (as shown in Figure 2 below); Step 3, tighten the thread (as shown in Figure 3 below). Repeat the knitting until the length is 6.5 cm (based on the hand circumference size 16 cm), as shown in Figure 4 below.

5. Next, make a new button knot: Step 1: Wind the right line from right to left and press the left line (as shown in the following figure 1); Step 2: Turn the circle up once (as shown in Figure 2 below); Step 3: The right line is still, and the left line is compiled as shown in Figure 3 below; Step 4: The left line is fixed, and the right line is compiled as shown in Figure 4 below; Step 5: The right line is still, and the left line is compiled as shown in Figure 5 below; Step 6: Tighten the thread up and down (as shown in Figure 6 below). The total number of new knots is 5 (as shown in Figure 7 below).

6. Next, weave the bird's head knot until it is 6 cm in size (as shown in the figure below 1). Then weave a Niukou knot after it is 0.5 cm empty (as shown in Figure 2 below).

7. Cut off the extra thread with scissors, and then burn it with a lighter to make the extra thread stick to the button knot. At this point, this red rope bracelet with bird knot and cow knot is completed.
