I prefer to make my own cord, out of lace, it looks interesting, and
I can control how soft or hard I want it to be.
If you want soft leather, see if you can buy a stained leather cord
as opposed to a coated cord. You can get fancy and buy commercial
leather softeners or oils, or you can rub in Vaseline. The Vaseline
softens leather, and it protects it also.
I don’t know what Creatin is, or what it does to the structure of
Leather is basically skin, so it’s not the most durable product. The
softer it is the more wear it will sustain.
