Earlier this week, I introduced spaced connected fly stitches used to depict plants. Like I wrote before, the mid line of such a plant sprig can be whipped to make it more pronounced.
First, do a prig of connected fly stitches. If you want to depict a plant, pay attention to start it neatly and give it an organic form. Avoid making it too regular.
Next, whip the mid line like you would a row of back stitches. Always run the needle under the stitches from the same side so the thread goes over the midline stitches.
Behold the finished twig.
