The course of bonnet crochet is as follows:

1. Material preparation: Wool: Choose warm-colored wool suitable for winter, such as crimson, brown and dark blue. Crochet: Choose crochet with appropriate size, and generally use No.6 or No.7 crochet. Auxiliary tools such as scissors and thread clips.

2. Step: Weave the basic needle: First, crochet a long strip of basic needle according to the size of the individual's head circumference. You can crochet with single needle or double needle, and choose according to your personal preference. It is suggested that a few stitches should be hooked before starting to ensure the accuracy of the number of stitches and turns.

3. Increase the width: On the basis of the basic needle, increase the width of the hat by adding additional coils on both sides. These coils can be realized by adding extra crochet needles to the basic needles. It is recommended to add a coil every two turns. Continue to crochet: Continue to crochet until the height of the hat reaches the expected level.

4. In the process of crocheting, the number of loops can be increased or decreased as needed to adjust the height of the hat. Top treatment: At the top of the hat, you can continue to use the double-needle hook weaving method to achieve the tightening effect of the hat. At the same time, the single needle method can also be used for reinforcement to prevent the hat from being deformed.
