Fibonacci Swirl Hat (11 st version)

Hat Formula: Determine gauge and desired hat size (1-2" smaller than the head). Decide number of repeats (11 * 6, 7, 8, 9 or 10) based on the total stitch count. Note that some rows have 2 decreases and the stitch count changes. Work rows 1 - 26, rep rows 16-26. Increase 1 st to 12, work a 3/3 ribbed hem. Start with a circle cast on.

Shown with a cast-on count of 2 stitches.   Getting chart...
