Stitch pattern used in Starflower Hat by Connie Chang Chinchio in Textured Stitches.
Note that the original instructions in the book neglected to instruct the knitter to move the beginning-of-rounds marker at the start of rounds 7 and 15. As a result, the stitch map shown below has odd jogs in it. See also this errata page, a modified version of this stitch pattern that doesn’t involve moving the beginning-of-rounds marker, and this blog post about the process of coming up with the modified version.
Shown with a cast-on count of 24 stitches.
