Western Europe, from Normandy to the Netherlands, is recognized worldwide for the fineness and strength of its flax fibers. Thanks to its unique terroir and favorable climate with alternating rain and sun, the flax fibers will serve for the manufacture of medium to high-end yarns. Rooted in Norman traditions, flax guarantees a healthy balance between human activity and the preservation of the diversity of the landscapes and ecosystems. Dubbed a model at the European scale, flax culture meets all the economic, social, and environmental criteria of sustainable development.
