Knitting is a method for production of
textile fabrics by interlacing yarn loops with loops of the same or
other yarns. It is used to create many types of garments. Knitting may
be done by hand or by machine. Knitting creates stitches: loops of yarn
in a row, they can be either flat or in the round (tubular). There are
usually many active stitches on the knitting 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 so that the loops from the prior
row can be pulled off the other needle without unraveling. Differences
in yarn (varying in fibre type, weight, uniformity and twist), needle
size, and stitch type allow for a variety of knitted fabrics with
different properties, including color, texture, thickness, heat
retention, water resistance, and integrity.[1] A small sample of
knitwork is known as a swatch.
