Snailtrail Stitch. A useful stitch for stems and outlines in which a broken effect is required. Bring up the needle to the right side of the work. Hold the thread down under the left thumb ; pass the needle over the thread and insert it in the material on the left-hand side of the thread about an eighth of an inch from where it came out : bring it up again to the right side on the opposite side of the thread. Draw the thread through, when it will be found that a small straight stitch and a knot have been formed. Repeat the process at regular intervals.
