The actual name of this lace stitch is the Horizontal Lace Stitch #1 which we talked about in episode 21 of YaT. Adding the stitch pattern as a single line of detail or as the entire body of work will provide interest either way. This stitch is another of those super simple, super easy knitting bits. Enjoy.
