Had to learn lacing during my Electronic Engineering apprenticeship in the 1980s, but the skill has been little used since. I did, however end up with a large spool of waxed, flat nylon, lacing cord, to which I fixed a small metal nut. The cord was very light and I could throw the nut (and cord) quite large distances through roof spaces and ducts; it was a great method for pulling through data cables.
