The square boss stitch is worked nearly identically to the rice stitch, with the exception of shorter arms crossing the large base stitch. The shorter arms are worked closer to the center of the stitch.
This stitch can be used in borders and rows, to accent a hem, or as an individual element in an embroidery design. For example, the square boss stitch was used in the outer borders of the Northern Woods counted thread project.
This, and other versatile and useful stitches, can be found in the alphabetical embroidery stitches list.
