finding the perfect cord for a choker is a challenge!
I´m working on new Pendants - glass beads and wood, no metal, so approx 3 mm thick, not too flexible cords are needed.
leather cords are not abrasion resistant and get unsightly over a short time....
I did a test with flaxseed oil just to see what happens
...not very successful, I have to say. Maybe I should do another with hair conditioner .
next try ....high end shoe laces , they seem to be strong and they are available in different thicknesses,
unfortunately a bit too flexible as well to be used for chokers, but ok for some uses.
most suitable are these nappa leather cords, though they are sewn together, which I don´t much like .
Another idea I have in mind is to try strings for Instruments like harp or cello (ok, maybe nobody wants to have a catgut around his neck).
If there are new findings I will share it here.....and of course - any suggestions are welcome!
