Yes I have made charcloth- we used to carry a fire kit when hunting (also carried lighters, but they were not always reliable). Made our own charcloth- I used to make primitive things like arrow heads, knives from a local glass-like material (kinda like obsidian, but man made), bows, arrows, etc. We didn’t go quite to the extent that reenactors would go, but we did do some of the old “primitive” prep stuff like that. I had a huge chunk of flint from the cliffs of dover- white on the outside, black as coal inside. Still have it. Made the striker out of carbon steel file- worked pretty good.
The cloth would ca5ch the spark pretty well, even in high winds. Carried small bundle of tinder too.
