This stitch looks like series of crosses or Xs with a knot in between each X. Once you learn this stitch, you can experiment widely with this stitch by making various geometrical patterns like circles. You will then see how the same stitch could look differently wtih each pattern.
I will follow a slightly curved line. This stitch is done from left to right. The thinner the thread or bigger the base, the more it accentuates the feature of this stitch.
