Seed Stitch aka Moss Stitch
Seed stitch also know as Moss Stitch consists of single knits and purls that alternate horizontally and vertically. Seed stitch gets its name from the texture of the knitted fabric — the little purl bumps look like scattered seeds. Although a little more complicated than the garter and stockinette stitches, seed stitch creates an interesting texture and is included in many patterns.
Like garter stitch, seed stitch lies flat, making it a good edging for a sweater border and cuffs and its stretchy just like rib stitch. The knitted fabric also looks the same from both sides, making it a nice choice for scarves and other pieces of which both sides are visible.
