How to crochet the watermelon hat with the same paragraph in Li Xuejian?

Li Xuejian's watermelon hat is crocheted, and the number of stitches needed for the head shape is enough with wool, and then it is looped and knitted into a tube shape with four stick needles in turn, and the length is enough to sew one end together, so that the watermelon hat is made. The weaving method is that the twist of 1 stitches is unchanged, the front side is 2 stitches, the front side is added with 1 stitch, the back side is not added with needles, and the side is a row of positive stitches and a row of negative stitches with 1 stitches (washboard stitches), and then the stitches are added here in the same way (both sides are next to the edges of 1 stitches), and then the patterns of copper coins (three stitches), twists and edges are woven. When knitting to a certain length, reduce the needle. The position of reducing the needle is the same as that of adding the needle. The position of reducing the first needle should be the same as that of adding the last needle, and it must be symmetrical. This is the whole process of knitting the watermelon baby hat.
