Units of measurement
★Yarn count is a way to grade flax according to the fineness of fiber.

◆1LEA=1 pound flax spun 300 yards (yarn)
◆40LEA=1 pound flax spinning 40 × 300 yards (1200 yards)
In Europe, metric count is adopted, which is expressed by the letter Nm, that is, Nm=fiber or yarn length meters/weight grams.
