Diagonal Shadow Stripes (multiple of 4 sts plus 2)
Note: this is a generic pattern for creating this stitch pattern. For a single repeat, it would be 4 stitches plus two additional stitches (but you'd have a VERY narrow piece!) In the example shown, there are seven repeats of the stitch, so to make the same, you need to cast on 30 stitches (7 x the 4 multiple plus the 2 extra stitches.) p1-b (p 1 in row below)
Row 1 and all WS rows Knit.
Row 2 (RS) P1, *p1-b, p3; rep from *, end p1.
