Why does my stockinette stitch look like a basic stitch?
Are you knitting? If by basic stitch, you mean garter stitch, it
is because you are knitting on both sides of the work. It may also
mean your working yarn is in the wrong place when you attempt to
pearl a stitch.
A stockinette stitch is achieved by knitting on one side of the
work and pearling on the other. When knitting, the working yarn
should be at the back of the work, away from you.
When pearling, the working yarn should be pulled between the
needle and the work,( closest to you) and then work the stitch the
same as a knit stitch. This should fix your problem, but if not,
please ask more questions.
