How-To Video https://youtu.be/W1ULBCppo7M
This pattern requires 4sts plus 2 extra. In the image above I used 22 sts and repeated the pattern 4 times in total.
Row 1 (K2, P2) to the last 2 stitches, K2
Row 2 (P2, K2) to the last 2 stitches, P2
Row 3 (P2, K2) to the last 2 stitches, P2
Row 4 (K2, P2) to the last 2 stitches, K2
Repeat these 4 rows.
To create this moss stitch in the round, cast on a multiple of 4 sts.
1st and 2nd rounds (K2, P2) to end
3rd and 4th rounds (P2, K2) to end
Repeat these 4 rounds
