Your scarf sound luscious, Adrian! Don't forget that your fringe can be part of your tie-on to your rod. If you tie your warp on securely, but carefully - it should be relatively easy to undo it and twist it into your fringe. Jane suggests tieing on in segments of no more than 1" but I think you could go less than that. It will give you a solid base to weave your spreader rows, then do your hemstitching and start your scarf. If you are worried about including that warp in the tie-on, then just start measuring after you've tied on and you can include your spreader rows in the fringe area. You can carefully cut that weft out after you take your beautiful scarf off the loom. Photos please!
