KNITPRO Nova Cubics fixed circular needles suit knitters who want a steadier, square-profile tool for controlled knitting. This 100 cm needle (about 39 inches) in 4.00mm is suited to everyday garments, hats, and accessories in light to medium yarns and holds a larger stitch count on the cable. The fixed circular format helps keep the work supported as it grows, which can make it easier to maintain consistent stitch formation when working flat or in the round.
