I learned how to do lacing during an electronics engineering apprenticeship in the 1980s.

After the fact, when I moved more in to systems and networking, I found that flat, nylon, waxed lacing cord, with a small nut tied to the end, was lightweight and perfect for throwing through ducting and ceiling spaces very long distances, so you could backhaul cables through the void. It was a real time saver.
