The one I am in the process of making, I bought about 150 feet, though I haven't used it all, and had to strip the blue plastic stuff off of the outside which revealed 4 twisted pairs of wires. I then have to untwist those, and braid them into strands of three. Once I have about umm, it feels like fourty but I am in Maryland at the moment and can't say exactly, I further braid three already braided units together. Once that is done, I braid three of those and finally I think I get to terminate, cut them down, and see what they sound like. I am completed stage one, the three strand braids and hope to be finished with stage two tomorrow evening after work. Mine are about 10 feet fwiw, though I would like to get a 15 feet pair for the surrounds done at some point as well.
