Help with a stitch/technique?

I am expanding my knitting and came across a photo of a stitch/technique I can’t find. If anyone can share a link or description of this edging stitch, please do so. I would love to use it on my hats and leg warmers.

Welcome to the forum!
it looks like a version of cross stitch.

It’s knit on rather large needles in your photo which gives it that wonderful open look.
it’s indeed a very pretty stitch pattern.
