Summary from website:

I love the almost architectural structure of the hat -- the pattern reminds me of columns and a facade. Although it’s simple to knit, I found it a little tedious, so it is a good pattern to knit when you are supposed to be paying attention to something (or someone) else. I did get a little overconfident in the repetition and twice had to go back to undo where I’d lost the rib pattern.

Variation:

to make a more unisex hat, the border can be replaced by a lace or ruffle option.

Notes:

Uses Circular Needles, 16” long, & DPNs.
Hat is knit from brim upwards to crown.
