This is really an extended swatch, done with reverse stitches.
For the box stitch pattern,
I alternated Reverse Purled Post stitches with Post stitches.
Then I turned the fabric around
and did the Reversed Purled Post stitches on the backwards Post Stitches, and vice versa.
For the (far stretchier) striped sections,
I just did the Purled Post stitch,
then turned it around and did the Purled Post stitch into the reversed row.
which looks about the same on the other side:
I’ve also been busy adding some of these novel stitch combos to Stitch Gallery 2.
