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.
The process of knitting has three basic tasks:
the active (unsecured) stitches must be held so they don't drop
these stitches must be released sometime after they are secured
new bights of yarn must be passed through the fabric, usually through
active stitches, thus securing them.
