The technical mastery and know-how of flax growers play a major role in the production of high-quality linen fibers. Harvesting the flax straw is a crucial moment that requires precise timing. Too early, the still damp flax would not easily lose its straw matrix. Too late, the fibers would dry and brittle. When the timing is optimal, the flax grower must be responsive to wind the retted flax straw as the slightest dew would affect the quality of the fiber.
