Sewing to wrong side

Hi everyone
I have picked up stitches along sweater for neckband and knitted a 2 inch rib neckband. It says to fold neckband in half to wrong side and sew loosely. What kind of stitch do I use to do this and keep it loose.

I use a simple stitch where I pick up a loop from the cast off edge and then from the seam made when you initially picked up the sts. Don’t pull the yarn tightly, just enough to pull the strand through. That’s enough to secure the neckband. It also helps to pin the neckband in place first so that you can stitch it down evenly and not skewed.
