1. Mark the part to be cut (2-3 cm shorter than the cut length) and cut it decisively.

2. Then turn the cut part upside down and cut the trouser leg part.

3. Take apart the thread of the trouser leg with a knife.

4. After taking off the thread, cut off the thicker part of a suture as shown in the figure.

After the cut trouser leg is folded in and put on the end of the trouser leg, you will find that the end of the trouser leg is still the original part with wear marks.

6. Sew along the edge. If you don't have a sewing machine, you can take it to a clothing store for sewing.

7. Sew it right away.
