KNITPRO Basix fixed circular needles suit knitters who want a steady circular setup for flat rows or knitting in the round without switching needles. You get one 80 cm (31.5 in) circular needle in 2.25 mm for projects where this length helps manage stitch count and shaping. Select the length that fits your project circumference and check gauge early so fabric density stays consistent as you knit for more predictable results over longer rows.
