How to choose trouser legs

Choosing trouser legs seems simple, and choosing them well requires skill. The specific operation is as follows:

1, straighten the trousers to be sewn with the five fingers of the left hand;

2. At the joint of trouser leg and trouser leg, one-way single-line plus eight-character and inverted eight-character alternately pick seams. Too much cloth will cause fire, too much will expose needles, and too little will pick rags;

3. When picking, try to pick the eight characters as small as possible, so that the stitches are dense and strong.
