Knitting Needles, - A knitting needle or knitting pin is a long stick or rod used as a tool in the manufacture of hand knitted fabric. The needle is used to reach through a knitting stitch in order to snag a bight of yarn and pull a length back through the stitch to form a new loop at the top of the current wale of stitches. The simplest requirements of knitting needles are that they must be smooth, thin and long enough to reach through a stitch and strong enough not to break while manipulating the bight of yarn. Knitting needles, commonly used in pairs, are the only essential tools for hand knitting (Thomas, 1938; Hiatt, 1988).
