Tools: wool, knitting needles, scissors, sewing needles, wool balls or decorations.
Steps:
1. Measure the head circumference and subtract 1-2 cm to ensure that the hat is not too tight.
2. Start knitting and choose different knitting methods such as plain knitting or rib knitting. Beginners can start with a flat needle.
3. Weave to a certain length and close the needle to form a round cap.
4. Fix the sewing needle to prevent the hat from falling off.
5. Add decorations such as wool balls, tassels or patches to increase the sense of fashion.
6. Cut the thread with scissors, arrange the hat and finish the production.
