Double-pointed needles with a twist - or flexibility rather! The latest way to knit socks. These double-pointed knitting needles have a short section of cord in the middle of each one, allowing it to bend.
With this 3-piece set of flexible sock knitting needles even really small diameter pieces can be knitted very easily. For knitting in the round, the stitches are distributed over two needles and the third needle is used for knitting - meaning only two needle changes per row.
