Ribbed Throw Pattern Help

[Dexter]

Hello! What pattern / needle size / yarn type would you guys use to create a ribbed throw similar to the one attached? I really like the look of it, but I am not quite sure how to recreate it myself. Thank you for your input!

It looks like a pretty bulky yarn in a k3 p3 pattern.

Or even a worsted weight. I'd do size 10.
