Bind off help

I consider myself a pretty good knitter but I’m having an issue with how to bind off my current project. It’s a baby blanket done completely in stockinette. I started to bind off with a picot edge but didn’t like the look of it. Any other suggestions for bind off that won’t let the stitches roll? Or should I just do a few rounds of garter and then bind off?

If you do a few rounds of garter then bind off, I’d pick-up stitches on the other end and do the same number of rounds of garter stitch to make it even.

I’ve also found that binding off with a crochet hook seems to make an edge that lies flatter even with stockinette projects.
