So... YouTube started recommending videos about making paper and ink from grass and leaves...
In case you need to save a civilization, here are the tips:
1. use grass to make paper instead of leaves, unless you don't really have an option.
2. Leaves can be a good material to make ink
3. With old technics, you often need large amount of things to work. Small batches may fail.
