Also, if you can get your hands on a copy of "Doin' the Twist", there's loads of good info in there. Great vid on string making, featuring a very notable string maker, Chad Weaver.
The other guy in there (I forget his name) also had some very good pointers, and I was able to mix the two methods to get my recipe which has been effective.
Though you've already made a jig, just for your gee wiz the only thing you really need to make a string is a spool of material, a knife or scissors, some means of measurement like a tape measure, and wax. Then you just need a server and serving material and you're golden.
