Brilliant pattern!

I’m a loose knitter so had to go down several needle sizes from the one the pattern indicated to get a nice fabric. No gauge given in the pattern, so I swatched until I liked the density/drape of the fabric.

Ribbed brim worked in US#4
Body of hat worked in US#6

Knit rib for 3 inches, for a fold up brim.

I believe the setup round should read:
K13, kfb, p2, repeat around to marker
This gives a repeat of 17 stitches.
Total 85 stitches for the hat body

Knit 4 pattern repeats before starting the decreases.

Didn’t use the whole skein… see photo to compare what was left from one skein.
