Knitting needles come in all shapes and sizes, but they are also available in a variety of materials. These can make all the difference. The most popular are bamboo, plastic and metal needles. You will need to think about both the yarn you are using and your own skill level when selecting your knitting needles. If you are a beginner, avoid slippery needles (such as metal and plastic) as your points may slip. More experienced knitters may prefer slicker needles because their stitches will slip more easily and more quickly.
The bamboo needles are light and comfortable to hold. They have a slightly textured surface and keep the stitches in place. Bamboo needles tend to work well with all kinds of yarn, but are more used with smooth and light yarns. They are rather flexible which is an advantage. The smaller ones will tend to break more easily than other types of needles.
Unlike bamboo needles, metal needles are very durable and therefore do not bend easily (or break). However, they are heavier and colder to the touch. Their smoother surface allows faster knitting because the stitches can slide without friction, making them a preferred choice for the most experienced knitters. Metal needles are suitable for all types of yarn, but work best with wool (including wool blends) and acrylic.
Plastic needles are just as smooth as metal needles, but are much lighter and more flexible (even more so than bamboo). They work great for any wire, but are especially good for larger threads that require a larger needle size because they will not be as heavy as other types of needles
Wooden needles are not slippery (just like bamboo ones), but they always have a greater sensation of softness than bamboo ones. They are perfect for beginner or experienced knitters and work very well with threads that tend to slip (like silk for example). You can find a variety of wooden needles, but hardwoods are the best because they will be stronger. However, like bamboo, wooden needles tend to break (especially in small sizes).
When you start a project, try to think about the material you will use and its effectiveness with the needles you want to use. After, no stress, if you love bamboo needles and can only see through this, you will not be disowned by the community of knitters or punished by the Holy Skein.
Find the type of needle that suits you best, listen to your wishes and knit with joy! 😛
