If you have had a difficult time working a cable on your knitted project, this tip may help.
Use a aluminum crochet hook as the stitch holder, that use that hook to make the new stitches, instead of trying to knit them off of the stitch holder.
I've always had a hard time knitting the stitches that are being held aside for the cable twist. My knitting is usually too tight to make the crossover easily, and try as I might I couldn't easily knit the stitches off of the cable needle. So I got the idea of using an aluminum crochet hook similar in size to my stitches as a stitch holder, then hooking the yarn to make the new stitches, instead of knitting the new stitches off of a stitch holder needle, or cable needle.
The aluminum hook I'm using is a size B (2.25 mm) by Boye, it has a matte or powder finish to it that helps hold the yarn on the hook. I place the stitches on the hook body that I want to hold for the twist of the cable, then knit the other half of the cable stitches. I place the held back stitches back on the left needle from the hook, then with the first held back stitch, start hooking the yarn and placing the new stitches on the right needle, adjusting the tension as the stitch is placed on the knitting needle.
Doing the cable twist this way has made for a easier and neater result in the cable twist. It eliminates the strain on the stitches that need to be knitted at the crossover, from trying to reach them with the right side knitting needle.
I've used this trick for other knitting projects, when working with twisted stitches. One of the decreases that I like to use twists the stitches in the opposite direction from how they normally sit on the needle, and it is easier to pull the yarn thru those twisted stitches with a hook then grabbing them with the right knitting needle. I knit thru the back loop instead of from the front/left; when I twist my stitches they are then facing front/left, and therefore somewhat tight compared to the other stitches in the same row. The hook makes it easy to grab the yarn and pull it thru the tight stitches without splitting the stitches or the yarn.
Enjoy! Edey
