From "The Gentle Art of Stitching" by Jane Brocket. Here are illustrated examples of Kantha, a traditional form of handwork in rural India and Bangladesh encompassing a wide range of design that uses only the running stitches.
I ❤ embroidery . . . The Running Stitch & Finishing Threads~ The most basic hand embroidery stitch. It is simply an “up and down” stitch in the fabric. Even though it’s such a basic embroidery stitch, there are many, many things you can do with it! Running stitch can be used quite effectively in all levels of hand embroidery. Don’t overlook it as a possibility in even the most complex types of hand embroidery.
