Instead of sail ties, I like to use a single rope with this knot:
The knot is started on the left in this example (as if you were standing on the starboard side facing the boom and tying the end of the sail first). It starts with a simple loop. You can use a slip knot, if you want, for faster untying. Then you bring the rope forward a bit, take a bight (a "U shaped bit of rope") and wrap it around the sail bundle and after that tuck it under the rope and push the remaining 1-2 feet of it forward, but don't pull all the rope through. Instead, you reach behind the sail, grab another bight, bring that forward and after wrapping the sail in the other direction, tuck it through the first bight and push it forward a foot or so. Rinse and repeat. At the end, tie off with slip knot.
More complicated to describe than do. Try it sometime with a blanket roll like in my picture.
The beauty is, once you untie it, you only pull on the free end an the whole thing unravels. You also never pull through more than 2-3 feet of rope (doubled in a bight) at one time making the tying a quick affair as well. And you don't need to have dedicated sail ties; when not securing your sail, that rope is free for some other purpose.
PS: I'm sure this tying technique has a standard name. Perhaps someone knows it, which would enable people to google better tying demos.
