From the blog:

After casting on three stitches and working two rows to get started, the 4-row repeat begins. Every right side row starts with a yarn over that is not worked off with a corresponding decrease and every other RS row ends similarly, resulting in the growth and shaping of the piece.

The “star stitch” decrease … reduces every three stitches to two and does not produce a bias fabric like yo, k2tog.

My doll-size sample was knit with fingering weight wool on 3.75mm needles. I worked 60 rows and the piece blocked to 11¾“ wide, 6” long.
