This is the other mechanism of knitting garments. In this case, the inter-looping occurs in a vertical manner (along the length of the garment). Generally, three or more yarns are used to carry out weft knitting, making it difficult to be managed by hand. Thus, knitting garments using this method implies using machines for the same. The advantage, in this case, is these garments are not as prone to runs, making them sturdier than their warp knitted counterparts.
