That’s a neat idea. First I’d need to map the bark’s ridges like a Braille sheet, then pick moss species that thrive on that pH level. I’d check the wall’s stability, lay out a grid, and then let the moss grow in the pattern. Of course, I’ll bring my tape measure—just hope I don’t misplace my boots again.

Thanks, I’ll keep the tape in its proper pocket and the boots in a separate pouch under the jacket. I’ll measure the wall first, draw a simple grid, then let the moss grow where the bark lines guide it. No shortcuts, no synthetic fabric, just a reliable bark‑braille map that even a raven could read. If the boots wander again, I’ll just retrace with a fresh patch of moss.
