From The Lacy Knitting of Mary Schiffmann by Nancy Nehring. Note that the original pattern contained an error in row 27.
I like the contrast between the single-yo mesh forming the bulk of the triangle points, and the double-yo mesh along the sides of the triangle points. I also like the lacy loops created at the left edge by starting each WS row with a yarn over.
Shown with a cast-on count of 30 stitches.
