    Waxed linen is incredibly strong and reasonably weather resistant. Waxed hemp is also known but quality varies significantly - large chunks of fiber looks more like baling twine instead of string.

    I don't know what is used on the strain relief but don't go with anything using synthetic fibers or fiber blends. The wax will swell/weaken most synthetics.

    Looking for things called cable lacing cord, string, tape, or twine.

    Lacing cord. It was used extensively in WWII surplus electronics but now seems to be relegated to special cases when plastic wire ties just won't do.

    It has been largely replaced with plastic alternatives, such as spiral wrap etc.
    Used to be very common at one time, it is just too time intensive now.
    You can probably still get waxed twine from a cobbler supply shop or wholesaler.

    I found it very good, to secure it, if needed, there is double sided tape backed pads to hold it in place by way of a tie wrap.
    Google 'Tie wrap adhesive pads"

    It won't give you the flexibility or hold of a traditional wire harness. With cable lacing, branches are held very securely. Nothing compares with the workmanship of someone who knows how to lace cables.

    When I was in school (4 decades ago), we were taught how to do it; because many of our graduates ended up working for Tektronix where cable lacing was used extensively.

    I disagree about the lack of holding capability, any slight difference is outweighed be the speed of use , convenience etc, the best way is to pick up a few feet and personally assess it.
    Most local electrical suppliers usually stock it or a local panel builder might sell you a few feet.

    in 8th grade, an art teacher had us make waxed linen jewelry with knots/beads. I thought the material was excellent for many things since. I've used it to hand-sew rabbit fur/sheepskin mittens and repaired leather motorcycle seat on an Indian (not mine) and several other projects. I always have a few spools in the house. I've never thought of it for cable straps until this thread.

    Except it was not replaced by Zip Ties, as stated.

    It's called "lacing cord" and it's basically either a woven Nylon or Dacron tube flattened into a ribbon and filled with a wax to keep the knots on single ties from loosening. Different widths are available from the usual suspects in order to fulfill the requirements of the job at hand.

    My favorite tie is a single clove hitch finished with a square knot on the far side of the cable, kinda like these: Deice System Tester.jpg Emergency Battery Tester.jpg

    I used to lace all my harnesses, but decided to try spiral looming for a project. Sub-branches are difficult with this and where there is an oversized connection, it is difficult to make a neat bundle. I prefer lacing and feel it produces neater harnesses over zip ties.
