Whether you stitch the ends, or tape them down: make sure you tighten the knot like crazy.
A water knot that loosens up can 'move' along the sling, to very bad consequences. I have personally seen a case where someone was using a sling they had knotted themselves - and on which they had taped down the loose ends - where the knot had moved along the sling past the tape join - so the *only* thing holding that sling together was the tape.
In retrospect this seems almost unbelievable, and utterly careless - but it did happen, and my friend would have been in the shit if he leaned back on the sling, as he was just about to.
