I stumbled across this stitch on Pinterest* a few months ago. I had never seen it before and have used it multiple times since. It looks complex, but is the farthest thing from it. I named the stitch Horizontal Pairs.
The amount of symmetry in this stitch makes it so easy. I named it as I did to draw your attention to the fact each row of pairs aligns on the horizontal axis. Add two stitches over two rows, skip two rows on the horizontal, and repeat. It's that easy! (Just don't forget to change directions between the complete horizontal rows.)
The end result looks far more advanced than the stitch really is. I love it so!
As for threads, virtually anything works. So far, I've only done the stitch in one color with one thread. The stitched sample on Instagram uses Vineyard Silk on 18-mesh. It would look great with rows in alternating colors or thread finishes.
