Eco 4ply has a simple construction of 2/7nm giving 350m (383 yds) per 100g. Eco 4ply uses wool which comes from Peruvian highland sheep near where the yarn is spun reducing the carbon footprint of the yarn. The sheep are a cross between merino and corriedale breed valuable for the fibre length and strength they create. The yarn is an inexpensive alternative 100% wool yarn which is slightly more rustic in nature. Peruvian Highland wool wears well, has plenty of bounce and volume and is not prone to fuzzing and pilling. A great all purpose yarn.
