Net (device)

Grid-like structure of threads or yarns

A net comprises threads or yarns knotted and twisted into a grid-like structure which blocks the passage of large items, while letting small items and fluids pass. It requires less material than something sheet-like, and provides a degree of transparency, as well as flexibility and lightness. Nets have been constructed by human beings since at least the Mesolithic period for use in capturing or retaining things.
