How do you get stockinette stitch to lay flat?
If you knit the stockinette stitch back and forth, flat, you have to do one row of knit stitches. And then one row of purl stitches. These two rows are then repeated until the desired length. The stockinette worked flat will curl at all four edges.
Which is the wrong side row in stocking stitch?
The easiest way to distinguish the sides is to look at a simple swatch in Stockinette Stitch. The flat side with all the V’s on it is the “right” side. The bumpy purl side is the “wrong” side.
