This House Nordic Esme hallway runner is made entirely of PET yarn. PET yarn is made of recycled plastic bottles, and then spun into a thin polyester thread. The process from recycled plastic to a finished rug is long and time consuming, which in itself is a unique and sustainable project. The result is a beautiful and soft rug which looks and feels like wool. The Esme rug is suitable for both indoor and outdoor. At the same time, it is durable and easy to clean.
