Hey RR,
This is the basic knot and the one most net makers use pretty well exclusively. It is called the Sheet Bend, Weaver's Knot, Net Knot, well, you get the idea.
You might also find something
here, of interest. Asemery, who is involved with this site, is a skilled netmaker and he has made some beautiful nets. Also a very nice guy, who loves to answer questions.
The technique lotoblades is probably describing is hanging a bunch of cords and alternating which pair you tie overhand knots in. This technique works but is much slower than proper netting techniques. It has the advantage that once you see it, you probably won't forget it.
If you're interested in netting, take a little bit of time to learn proper technique. It's not hard, doesn't take very long, and it's a very useful and versatile skill.
If you have any other questions, feel free.
