Weft Knitting Manufacture. Weft knitting is a knitted piece of fabric where the stitches run from left to right horizontally across the fabric. It is usually knitted with one piece of yarn, and can be made either by hand or using a knitting machine.
It is a plain weft-faced weave having weft threads of different colours worked over portions of the warp to form the design. Most weavers use a naturally based warp thread such as linen or cotton. The weft threads are usually wool or cotton, but may include silk, gold, silver, or other alternatives.
