Making custom pattern. Help adding edging to eyelet pattern while knitting please!

[deljuego11]

Hi everyone. I am a fairly new knitter. I want to make a scarf with this simple eyelet pattern, but I also want to add a simple edging as well while I'm knitting (instead of picking up after). Something fairly uncomplicated that I can work into the existing pattern would be very helpful. I need it to be knit, crochet is not an option for me at this time.

Any hints or ideas? My purpose is to make a pretty edging, but also to help it not curl.

Thanks!
