From prehistoric fishing nets, weaving and construction to maritime essentials, the cultural origins of knots, their symbolism and universal language is enduring. Knots may be functional, ornamental, ceremonial, hard-working, even life-saving. Their construction can be simple or complicated, they can be practical or decorative, but they are all beautiful. The natural balance of the curves as they overlap and interlock, the simple engineering of tension and resistance and the contradiction of strength yet softness, knots are a natural harmony of design.
