Plastic needles are similar to wooden or bamboo needles in terms of lightness and smoothness, but they lack warmth. They’re also very smooth like metal needles so they allow you to knit quickly and are more flexible than other needles. Larger size needles are often made from plastic to reduce their weight.
There are three basic types of knitting needle which each have a different function.
1. Single point knitting needles are used in pairs to knit flat pieces. Straight and rigid, they are considered the standard needles.
2. Double point needles have points at both ends and are used in sets of four. They knit seamless, circular items such as hats, socks, gloves etc.
