Knitpro Basix have just the right tools for your extreme knitting. These circular knitting 'logs' are 25mm thick and are available with your choice of an 80cm, 100cm or 120 cm cord. This makes them perfect for knitting roving and any extra thick yarn. Great for felted wool too. The length of the cord allows you to rest your heavy knitting in your lap, taking the weight from your hands and arms.
