Based on jcbriar's Stained Glass Windows with bunny ears decreases, which was based on Stained Glass Windows.
When possible, work "CO 1 st" by picking up and working into the middle stitch of the Bunny Ears decrease from two rows before.
The M1R/M1L increases can be worked either as true M1 increases or by making yarnovers on that row, and twisting them on the purl row.
(The swatch photo shows only half a repeat, by the way.)
Shown with a cast-on count of 28 stitches.
