How to add stitches after knitting the sweater hem?

Tools/raw materials: needles, wool.

1, sew 5 stitches first, as shown below.

2. After knitting the first stitch, as shown in the figure below, wind the wool on the right stitch from bottom to top to complete the empty addition of 1 stitch, and then complete the knitting of this row downward, as shown in the figure below.

3. When knitting empty needles in reverse, as shown in the figure below, pick the needles from outside to inside and darn them in reverse. If you weave like other needles, you will leave an ugly hole, as shown below.

4. After picking the needle, wind it according to the method shown in the figure below, and then take it out with a stick needle, as shown in the figure below.

5. After the winding is taken out, as shown in the figure below, the thread end is facing itself, as shown in the figure below.

6. Go around the needle by hand and return to the normal position, and then knit the last needle, as shown in the figure below.
