The steps for knitting the octagonal hat and Tang monk hat are as follows:

Materials:

Cotton thread or wool thread

Hand-knitting needle (or straight Needle)

Steps:

1. Measure the head circumference: Use a soft ruler or wire to measure the head circumference to determine the required hat size.

2. Start knitting: Determine the required starting number of turns based on the measured head circumference. Usually start with 6 or 8 turns, which will determine the height of the octagonal cap.

3. Knit the bottom: Use pins to hold the threads together and then begin basic knitting. You can use flat or straight stitches, depending on your personal preference. Starting from the bottom of the hat, knit in a clockwise direction.

4. Add or remove stitches: The diameter of the bottom of the hat should be equivalent to the circumference of the head. If you need to add or subtract stitches, add or subtract some stitches where needed. This ensures that the hat fits your head snugly.

5. Knit the octagon: When the height of the hat reaches the desired height, start knitting the edge of the octagon. Select an edge line and start knitting, following the shape of an octagon.

6. Edge treatment: After completing the octagonal weaving, you can choose to add some decoration or embellishment to the edge of the hat, such as lace. This is a step based on personal preference.

7. Finishing: Finally, trim the threads and make sure the hat is strong and neat.

Notes on knitting hats

1. Choose the right material: Choose the right wire according to the purpose of the hat and the season. For example, for a winter hat, choose a thick, warm woolen thread.

2. Determine the appropriate needle size: Select the appropriate needle size based on the thickness of the selected wire. If the thread is too thin, you can choose a smaller needle size; if the thread is too thick, you can choose a larger needle size.

3. Measure head circumference: Use a soft ruler or hat circumference method to accurately measure head circumference. This ensures that the knitted hat is the correct size.

4. Choose the appropriate knitting pattern: Choose the appropriate knitting pattern based on personal preference and skill level. For beginners, simple basic knitting patterns such as jersey, knit and braid patterns are all good choices.

5. Pay attention to details: During the weaving process, pay special attention to details to ensure that each row is woven correctly according to the pattern. You can use pins or counters to help track your knitting progress.
