How does the loom weave brocade?

Weaving is weaving with a loom, which is different from ordinary weaving equipment. Only two healds are used to weave plain cloth, and at least five healds are needed for brocade. Each heald is connected with a pedal, and the pedal pushes the heald to stagger the warp yarns up and down. You can only step on two pieces at a time, in turn, or repeatedly, or after you finish retreating.

The woven pattern is relatively simple, and it is better to choose a variety of patterns, and they are all symmetrical and uniform. Generally used for brocade.
