Single twist 100% Nepalese hemp twine. Approx 1mm thick but as it’s a hand made product the gauge is not consistent. It has the odd thick and thin bit throughout giving it its rustic character. Note: it’s wound double onto the ball as pictured. I use it double directly from the ball, but have successfully separated to make two balls of single twine. They are hand wound and the weight varies, the minimum weight being 95gms. I made the two crochet hemp and vine baskets listed on my site with one ball.
