The knit stitch is a fundamental technique in knitting, where the yarn is looped through itself to create a fabric. To perform a knit stitch, the knitter inserts the needle into the front of the stitch on the left needle, wraps the yarn around the right needle, and pulls it through to form a new stitch on the right needle. This process is repeated across the row. Knit stitches can be combined with other techniques to create various patterns and textures. For example, alternating knit stitches with purl stitches results in a ribbing effect, commonly used in cuffs and edges of garments.
