Lacing cord is (or was) available both waxed and unwaxed. I've seen black, white, off-white and khaki (once). I hated the unwaxed because it was harder to keep the tension when tying a knot. But they might have had different purposes. I was building cables with expandable sleeving over them and we usually wanted as tight as possible to keep things from moving when the cables were handled, relocated, etc. For wiring harnesses in a chassis, it might be undesirable to 'strangle' the wires in the bundle (for multiple reasons), especially if PVC, and totally unnecessary because no one is stressing a chassis wiring harness by carrying it from a hanging rack to a factory test fixture or to a vehicle in the field.
So when unwaxed was what was on the shelf, I'd complain and someone would give me a partial spool of waxed because he knew where to get another full spool.
I always thought waxed dental tape for home use, also. But I haven't used it at home yet. I don't want minty floss and like the look of black...but there doesn't seem to be a market for black dental floss. Maybe in Montana? It seems like you'd have an immediate visible process indicator for when to stop.
The guy who taught me how to tie basic knots that sufficed for cable-building would always repeat himself admiring a retiree's continuous lacing for harnesses. I never needed that so I never learned. I bet it's in a book somewhere that has been scanned & archived. I'll go look.

There is a lot of vocabulary in this. Cable forms seem to start around page 104-105 +/- or so. If you start backscrolling there is info on color-striped wiring which is probably completely irrelevant and unlikely in consumer gear. It sux when it's PVC and the colors fade (just like with resistors) except with color-striped wire, any combination is possible, but with resistors you can sanity check against standard/preferred values or use an ohmmeter. Same with checking continuity on wiring whose color doesn't make sense (or colorblindness exists), but that doesn't solve every dilemma and the language becomes colorful.
I didn't read the whole document. I imagine there might be instructions on cable lacing, and you don't need more than 1 or 2 or 3 methods to have survival skills.
These TPUB books used to be downloadable free several years ago, and you could find Army or Navy electronics training. The website below seems offer the docs for purchase but use online is free. A lot of standards were retired (or some other vintage term...not deprecated...abandoned?)
Ooh...here, NASA stuff
https://workmanship.nasa.gov/lib/insp/2%20books/links/sections/files/401.pdfThis one hangs up in download probably for an expired web security certificate. If you don't like that, search elsewhere for a different archive. NASA-STD-8739 (Rev 4A?) The pictures start around sheet 28 after the vocabulary/glossary. This stuff may put you to sleep faster than my posts.
