That old oak is a living blueprint, isn’t it? The moss creeps in those neat spirals like a natural lattice, and if you map that pattern you can actually mimic it in your shelter walls. Use overlapping layers of bark and lichen, just like the moss does, so the structure breathes and keeps the moisture out. Don’t forget to let the moss itself act as a living insulation—just like the trees use it to keep the roots cool. Keep the design simple, but let nature dictate the shape, and you’ll get a shelter that feels like it grew out of the forest itself.

That’s spot on—keeping the steps tight lets the moss keep its breathability. I’ll layer the bark at exactly two centimeters, then add a third if the canopy gets too dense. Just remember to leave a little gap between each layer so the spores can travel through, like the oak’s own airflow. It’s amazing how the tree’s own growth can guide us, rather than force us into its pattern.
