Knot that I know of...

The reason that shock cord is desirable (prehaps more so with hammock tarps, but also with tents and tent-tarps) is that silnylon and to a lesser extent polyeurethane coated nylon, will stretch slightly when under load. So if there is any wind, the fabric will stretch and the lines will be a bit slack in the morning. Using a short piece of shock cord at the end reduces that tension and can tighten to make up for any fabric stretch. I now have a cuben tarp, which has effectively no stretch, so the necessity for shock cord is really greatly reduced.

Glad I was able to share the knowledge and that someone was able to take something good from it.

Wow, that "Animated Knots by Grog" is really cool.

I like the animated Knots thing too. I learned to tie two basic knots from Hennessy Hammocks how-to videos. The lashing,and a variation of that prussik sliding knot. My other favorite is the butterfly knot, because you can put it in the middle of a line without pulling a bunch of line through, great for guy lines. Same with the clove hitch, really easy to make in the middle of the line without pulling the rest of the line through...I use for bear bagging with the PCT hang.
