Knitting is the process of interlooping yarn to create textile fabric made of interconnected loops, done by hand, machine or both.
Knitting creates stitches: loops of yarn in a row; the loops are created with a pair of knitting needles, which can either be straight and cylindrical or in the round with (often times plastic) tubes joining the ends of both. There are usually many active stitches on the needle at one time. Knitted fabric consists of a number of consecutive rows of connected loops that intermesh with the next and previous rows. As each row is formed, each newly created loop is pulled through one or more loops from the prior row and placed on the 'gaining needle' (the needle that is receiving newly created stitches) so that the loops from the prior row can be pulled off the other needle without unraveling.
