Circular knitting needles are an excellent alternative to straight knitting needles, and are much more versatile. Apart from knitting in the round to produce seamless garments, you can also knit back and forth as you would with conventional straight needles. They are much kinder to your wrists and arms as well, as the weight of the knitting will be held by the nylon cord and will rest in your lap. With straight needles, the weight of the knitting is entirely on the needles, which can be a problem for those of us with arthritic wrists.
We stock a variety of sizes of fixed circulars in 4 different lengths, all with a flexible cord. If the cord curls too much, soak the whole needle in hot (not boiling!) water for a few minutes to soften the cord, then you can gently straighten it between your finger and thumb.
