I haven’t looked yet, but this stitch pattern is probably available in a couple places, patterns. Someday I’ll try to find and link here. I really like it and would like to do in a much looser gauge and sport, fingering yarn. See what happens.

multiple of 4 plus 3 - worked base of 19
finished with rows of single crochet

Future note for self - put 1 extra stitch on end (left) side so as to get a more balanced look along each side.
