The Knit pro company came along and took the humble knitting needle and made it better, in looks and usability. They created new wooden needles, colourful, flexible and very pointy, inter-changeable circular needles, even cubic needles! They also came up with colour coded needles so less hassle matching up a pair!
Now the range and variety of needles available is staggering, colour coded Zing needles, perfect for double pointed sets for easy identification. The Symphonie cubics I love for sock knitting, the stitches are less likely to fall off and less chance of losing a needle.
Have a look at the range, it will keep increasing!
