Sample knit with Lily Sugar'nCream Cotton on US Size 9 needles. This is what the front of the fabric looks like.
This is what the back of the fabric looks like.
This is a super simple stitch. With only two rows, it is also easy to remember. I personally would add a few more stitches to neaten up the sides, maybe plain garter or seed stitch.
This stitch pattern is short and sweet, and produces a nice textured fabric.
The edges are pretty sloppy, so I recommend adding an extra stitch (at the minimum) on each side to neaten it up. Personally, I would add a seed stitch border, about 3-4 stitches on each side in addition to a few seed stitch rows at the top and bottom, which is my go-to method of preventing sloppy edges. Depends on your taste and what you plan to use the stitch for, of course!
