Classic Circular Pins 80cm Aluminum Rod The Circular knitting Pin has two pointed shanks joined by a long flexible cord. The cord is strong and smooth and allows the weight of the work to rest on the lap rather than on the needles. There is less strain on the hands and wrists as the Circular pin cord accommodate a large number of the stitches. Circular knitting pins can be used for flat and knitting in rounds. The length of the flexible cord will determine the size of the garment. The transition point where the shank is connected to the flexible cord is smooth for snag free stitches and is firmly fixed to avoid the cord separating while knitting.
