Well, I am happy to tell you that you probably already know how to knit it. If you know how to knit stockinette stitch (abbreviated st st), you're doing it.
Flip over your knitting!
The wrong side is now the right side. Which is why it has the name reverse stockinette as its name.
You will need to know the knit stitch and the purl stitch.

Keep repeating these two rows.
The bumpy side is the right side of the fabric and the smooth side with "V's" is the wrong side of the fabric.
