This is very easy! Instead of tying it like you would to make it in to an infinity scarf just tie it so it has "tails". You should still be able to wrap it a couple of times. It does mostly stay put, but you may have to move it around a little now and then. But if you criss cross (twist) the wraps once you have wrapped it, and make the knot sit on top of the crossed wraps instead of under, it tends to rest there better. Hope that made sense.
The slightly more difficult way to tie it is so the knot is adjustable (which I how I usually do them).
This is start of the adjustable knot I use for most things that are going to have a tail:

Put the other end through so it faces the opposite direction of the tail that has the knot in it:

you can tighten from either side of the knot. If you tighten the tail, you get a longer tail, so if you want less tail, tighten the side that runs up in to the scarf length. That's why I do this knot, because I often goof on how much tail I need (and you don't need a lot)

Stick it over you neck and wrap it! Then gently "braid" the wraps a couple of times to twist the wrap and make sure to place the knot and tail up on the topside.
Thank you for your kind comments!
