This KNITPRO Basix fixed circular needle pairs two needle tips with a permanent cord for knitting in the round or for flat rows when you need extra room for stitches. It is 100cm (about 39 in) overall with 4 mm tips, giving you space for larger rounds such as cowls, sweaters, or blankets while the cord holds the bulk of the fabric. Overall length is measured tip-to-tip, so you can match needle length to your pattern’s circumference and keep stitches comfortably on the cord.
