Moss stitch is like seed stitch but you work in rows of 2 rather than swapping every row.
Cast on an odd number of stitches, this will make the pattern symmetrical so you can have either side as the right side.
Rows 1 and 3: K1, P1 to end
Rows 2 and 4: P1, K1 to end
Try to finish on an even row as this will keep the balance of the pattern.
This swatch was done in Aran on 5mm needles.
