Work the first row of this stitch from right to left similar to Running Stitch, but with all stitches of equal lenght. On the return journey, work in the same way from left to right, filling in the spaces left by the first row.
This stitch is sometimes used as an outline to CrosssStitch designs, as in Assisi Embroidery, but a design can be worked entirely in Holbein Stitch. It should be worked over counted threads of fabric for the best results.
