Swatched and got 18 stitches / 4 inches
head 23 inches
cast on 100 stitches (100/18 = 5.55 X 4 = 22.22)

knit about an inch
purled a row to make a turn line
knit another inch
fold at turn line and knit next row together with cast-on row to make turned edge of hat.

will knit 1 inch stripes with a purl row on both top and bottom of the dark pink stripe (3 dark pink stripes) then finish rest of hat in light pink.

I did 3 rounds between each decrease row, cause the hat in the photo is oddly pointed. Dunno if I got it right, but I think it’ll work ok.

after done will pick up and add ear flaps and I cord strings.
