Circular needles can be used to perform the same tasks as the straight ones, which are: knitting flat pieces and working in rows. They can also be used for patterns that are worked in the round. This is particularly handy when creating cylindrical items, such as sleeves, snoods and cowls without a seam. Two things to consider; size of needle in mm for type of wool & length of cord for how many stitches you're putting up, 40/60/80/100 cm available.
