That sounds like a solid lead. The bark‑paper methods are pretty well documented, and they often tie into specific regional histories—like the use of pine bark in colonial America or birch in Scandinavia. If we can isolate the exact fiber extraction steps, we might find a low‑impact process that still echoes those old practices. Just be careful with the dates and sources; a single misquoted paper could throw the whole comparison off. But I’m intrigued—let’s see what you’ve uncovered.
