Did you try a search for knitted headbands to see if you could find one you like? I can't see detail in the photo but duplicating crochet with knit is at best challenging. If you really like this enough, you might want to learn to crochet so you could make this pattern.
Cheating is an option. . . . Cheaters never win and winners never cheat, but smart knitters who want to retain an iota of sanity do, cheerfully. ~~Kory Stamper
