From Pitsilised Koekirjad by Leili Reimann.
Note that the original chart is 64 rows tall and has lots of edge stitches, presumably in an attempt to mitigate biasing and provide straighter selvedges. Myself, I like this simplified version of the pattern: smaller, easier to memorize, and not overly prone to biasing.
Shown with a cast-on count of 16 stitches.
