Cast on for small 94 sts due to gauge. Went down 2 needle sizes.

For second roll I shifted stitches to size 3 temporarily since didn’t have duplicate size 4.

I love the blue and purple together. It might be better to have more of a contrast though to see the flower pattern.

Modifications
Knit to 6 1/2” then start crown shaping at faster rate.

K7 k2tog around
Knit plain row
Keep decreasing

Width 10”
Height 7 3/4”

This turned out the stated width for the large size although I don’t think it would fit a larger sized head well. Maybe if the yarn was wool there would be more stretch to it.

I love the double roll brim.
