K1f&b, k1 in same stitch

I’m knitting the IK “editor-in-chief” shrug from summer 2005 and am not sure how to do the decrease k1 f&b, k1 in same stitch, so one stitch makes three.

Where do you k1? Would you do it back in the front loop, so it’s k1f&b&f? Or k1 f&b then make 1? It’s opposite a k3tog decrease if that gives any insight.

Thanks!

Well since it’s the opposite of the k3 tog, I would do all three in one stitch.
