Seed Stitch
Seed stitch is made by alternating knit and purl stitch by stitch and row by row, giving the fabric an even, textured, grain-like surface.
Explanation
Seed stitch (also called moss stitch) is worked by alternating knit and purl stitches within the same row, then working the opposite of what you see (purl over knit, knit over purl) in the next row, so each stitch always meets the opposite type in the neighboring row. The result is a dense, textured surface resembling small seeds or grains, which lies completely flat without curling the way stockinette does. Seed stitch is often used for borders, entire garments with a rustic look, or as a contrast to smooth sections within a pattern.
