Purl & Knit Stitch for Sweater - Easy Knitting!

What I love about knit-and-purl stitches:
They are easy and endlessly variable. You can play with their unlimited combinations and applications.
Here is one of them good for cardigans and sweaters:

Multiple: 6+3 stitches.

Row 1 (right side): purl across.

Row 2 (wrong side): knit across.

Row 3: p4, k1, *p5, k1, repeat from *, end p4.

Row 4: repeat stitches as seen (knit over knitted stitches and purl over purled stitches).

Row 5: p3, *k3, p3, repeat from * to end.

Row 6: as row 4.

Next rows: repeat rows 1-6 as many times as you need.
