Provisional cast on with a crochet hook and a contrast color. I ran a lifeline through the first row using the hole in my chiaogoo cable to make it easier to pick up stitches later on

Size 6 needles
Knit a basic beanie using the yellow yarn.
Using orange yarn, pick up stitches at the brim of the hat and work 6-8 rows of alternating knit and purl to make garter stitch.

In the last row, isolate about 24 stitches and work back and forth using German Short row turns. After 4 rows. Make a stitch at each end ( one stitch in from the end) to allow the bill to flare out away from the wearer’s face, while still making the short row turns.
After the bill is long enough ( about 1.5”)
Begin binding off using stretchy castoff like Jeny’s amazingly stretchy bind off
