Steps:
1. Start from the first row. Start with even numbers.
2. In the second line, one needle is straight and the other is reverse.
3. In the third line, we began to weave the fishtail pattern. The first stitch is transferred directly without knitting.
4. The second stitch in the third row, before knitting the second stitch, wrap the thread from the outside to the inside and wrap it three times on the right stitch. As shown in the figure below. Then knit a second stitch. And so on. Finish this line.
5. In the fourth row, adjust the needle to the empty needle in turn with the empty needle.
5. In the fifth line, one stitch is correct, three stitches are combined into one stitch, and another stitch is knitted. Finish knitting this thread in turn. Then repeat the third, fourth and fifth lines.
