These three stitch patterns create an allover textured pattern using a combination of knit and purl stitches. As such, these three textured patterns are great for decorative borders. Between the USA and UK there is some confusion related to the Moss Stitch – I have seen references to the Moss Stitch which are exactly the same as what I know as a Seed Stitch here in the USA.

Seed Stitch (Moss Stitch):

This is one of my favorite patterns for borders with the stockinette stitch. It lies flat and does not roll or curl. It is reversible and I love it for front bands on cardigan sweaters.
This stitch pattern is a multiple of two and a repeat over two rows. The first row is the same as a 1 X 1 ribbing: K1, P1 across the row. On the following row, all stitches are worked the opposite of the way they face you – i.e. you purl the knit stitches and knit the purl stitches. Seed stitch tends to expand widthwise and is wider than the same number of stockinette stitches.

Irish Moss Stitch:

This stitch has a diagonal texture. It is a multiple of two stitches with a repeat over four rows. The first two rows are knit the same as 1 X 1 Ribbing: K1, P1 across the row. Then the next two rows are knit the opposite: P1, K1 across. You repeat these four rows to make the textured pattern.

Just like the Seed Stitch, the Irish Moss Stitch creates a reversible fabric that lies flat and does not roll or curl. The fabric will tend to expand crosswise and the stitches may “seat” themselves after washing. If you are using this pattern stitch as the main body of your garment, it is best to knit the garment to the actual measurements of the chest of the intended wearer before the first washing.

Double Moss Stitch (Double Seed Stitch, Box Stitch):

This stitch pattern is a multiple of four stitches repeated over four rows. The first two rows are the same as 2 X 2 Ribbing: K2, P2 across the row. On the next two rows, you do P2, K2 across. It has essentially the same properties as the Irish Moss Stitch. This pattern is wonderful for knitting textured scarves that do not roll or curl on the edges.
