In reply to Lupine Lacuna:
It's a lot more effort than folding, twisting, sticking them on a krab, but you can chain knot each sling, it stops them getting tangled, is quick to undo, and doesn't need a krab to stop them unravelling. Plus, if you chain knot a cordellette and two 240cm slings you can fashion a natty sit harness, probably utterly lethal but really quite comfortable.
