I suspect most furlers would not want to do it the way I do, but it works well for travel and will produce a furled leader of any length desired. My "jig" is a roughly 3' piece of 1x2 and a few pushpins. I furl in sections, knot each end before taking it off the jig to keep it from unfurling, and then knot the sections together. I've used several different materials, but usually use 6/0 Unithread, and find that a single surgeons knot holds well in Unithread and is not so large as to cause any problems. I do it this way because I don't have room for a full-sized jig, but I really don't see any downside to this method. It does take quite a bit longer, but I'm really not in any hurry.
