The bottom of the swatch shows this stitch pattern; the top shows Star Rib Mesh, which coordinates nicely. (start at row 2 of that version of Star Rib Mesh.)
Mourn version 2 is also meant to coordinate with version 1, but I have not yet made a swatch for it.
Thanks to my patreon backers for funding my stitch pattern design work!
