As can be seen from the illustration this version of fly stitch is simply arrangement of fly stitches that are one upon the other.
Fly stitch is worked easily since it is made up of a V-shaped loop which is then tied down by a vertical straight stitch.
To work simply lap each stitch over one another to form a pattern as in the illustration.
