How were ancient fishing nets made?

In ancient coastal areas, flax crops were planted and then flax thread was spun. So ancient fishing nets were made of hemp fiber, and some were mixed with coarse cloth and old clothes. Hemp fiber is easy to swell when absorbing water, and it is easy to rot when wet, so the fishing net should be dried for two days after two or three days to prolong the life of the fishing net. "Three days to fish and two days to dry the net" also comes from this. In the past, the fishing net was made of hemp fiber, which was easy to swell when absorbing water and rot when wet, so it took two or three days to prolong its life. There is no need to do this now, because the materials used to weave fishing nets are generally nylon fibers.
