The specific operations of handmade bag knitting are as follows:

1. In the first step, start with 10 stitches.

2. Knit both the front and back sides, but do not knit the first stitch of each row.

3. Use a knitting needle to lift up the other three sides.

4. Knit one stitch up, one stitch down, and tighten the stitches after knitting.

5. Use a crochet hook to double the thread and hook a belt.

6. Sew both ends of the strap to both sides of the bag to complete the specific steps of handmade bag weaving.
