The process of knitting has three basic tasks: (1) the active (unsecured) stitches must be held so they don't drop; (2) these stitches must be released sometime after they are secured; and (3) new bights of yarn must be passed through the fabric, usually through active stitches, thus securing them. Knitting as an art and a craft was kept alive only as a hobby
To carry all these tasks, you can make use of your fingers, without making use of any knitting tools, but in general practice knitting is done with the help of knitting tools, like knitting needles, knitting machine like rigid frames. If the fibers are first aligned by combing them, the yarn is smoother and called a worsted; by contrast, if the fibers are carded but not combed, the yarn is fuzzier and called woolen-spun. Extra curvature can be introduced into knitted garments without seams, as in the heel of a sock; the effect of darts, flares, etc.
Many knitters first become interested in the craft so that they can create blankets for their friends and family. In turn, the red loops secure the white loops just below them, which in turn secure the loops below them, and so on. The knit stitch is formed by making loops which interweave with one another; one after another.
All it consists of is knitting one row, then purling the next, and so on, and so on. You watch it come to life as you go, and little by little, your knitting becomes reality.
