This is an attempt to reverse engineer the stitch in the swatch at https://www.knittingkingdom.com/lace-butterfly-knit-stitch-chart/ , because the chart below it seems only vaguely related. (This was the topic of a question on Ravelry: https://www.ravelry.com/discuss/techniques/3904245/ )
Shown with a cast-on count of 29 stitches.
