LOVE KNITTING circular knitting needles are designed for knitting in the round and for holding wider flat pieces on a connected needle. This variant has a 40 cm (16 in) circular length with 5.5 mm (US 9) aluminum needles. The compact length is useful for small-circumference projects such as hats, sleeves, collars, and accessories when a pattern calls for a short circular needle. Match the needle size to the yarn and gauge listed in your instructions.
