Here’s a quick how-to video of the Outline Stitch (or Stem Stitch).
A great stitch for outlining and is an alternative to the Back Stitch. Pull stitch up from the back just on the bottom of the line you want to outline and pull thread taught. Bring back the needle just slightly on top of the line you want to outline. Your next stitch will start approximately half way of your previous stitch, coming up again just slightly on the bottom of the outline line.
This video has no sound to distract you from learning the stitch.
