Next, I produced a stockinette stitch sample, which alternate rows of knit and purl. Unlike garter stitch, the sample has a right side and a wrong side. The right side is smoother than garter stitch. The wrong side looks a little similar to garter stitch, but unlike garter stitch there aren't defined ridges. Stockinette also curls, both from top to bottom and left to right (you can see the top/bottom curl clearly in the picture of the right side, and the left/right curl in the picture of the wrong side).
