Over the past few years, I've tested out many different types of single point needles, especially while I've been working at a yarn store over the past year. I consider myself a "process knitter," in that I care as much about the actual knitting of the project as I do about the finished product. The needle that I find to be the highest quality is the Addi Turbo. It is important to take the quality of your needles seriously, as it can really improve your experience!
The first component I look for in a great knitting needle is the material that it is made out of. The type of material you want to use really depends upon your skill level. Bamboo is a great choice for beginners, as it really hugs the yarn when you're knitting, so you will not drop as many stitches. For advanced beginners through very advanced knitters, I recommend needles made out of metal, nickel or brass. The Addi Turbo needle is my favorite, because it is made from nickel and brass, so the yarn to slide very easily from one needle to the other. This can dramatically improve the speed of your knitting.
I would not recommend certain materials in bamboo crochet hooks, like plastic and aluminum. Acrylic needles and plastic needles feel too light and overly pliable for knitting. Aluminum needles feel like they're scraping against each other while you're knitting.
An interesting idea to consider is doing all of your knitting (flat and in the round) on circulars. All of my fellow employees use circular needles for all of their projects. This makes the process a little more manageable, and gives your projects more room (on the long cord.)
Because of this, I recommend using an interchangeable needle set. These sets come with needles of many different sizes and different lengths of cord. Choose the needle size you want, and then twist it into the correct cord size for your project. Addi carries a three sets of interchangeable needles called Addi Clicks. You can get Clicks in the traditional Addi Turbo needle, lace needles (made completely from brass), and bamboo. You never have to go and find a needle size again when you have a set. It also makes finding your gauge that much easier.
There are a few features to look for in bamboo knitting needles. The join between the cord and the needle should be as smooth as possible, so the yarn doesn't get caught while you're knitting. The cord should be flexible and of good quality. If you have a set, it should be impossible for the cord and the needle to untwist.
If you need to find the right needle size for a project, consult your pattern. Needle size is usually found in the "Materials" section of your pattern, at the beginning of the page. Look at the tag on your ball of yarn if you're not knitting from a pattern for a general size to use.
wood needles with every type of needle to see what is right for you. I find metal, nickel, and brass to be of the highest quality, but some people just prefer to knit with bamboo. Addi knitting needles come in many different types, so you are sure to find the needle that brings you the most pleasure and comfort. The process of making something beautiful should bring you joy, and knitting needles are a huge part of that!
