Thank you! That was something that I tried to research a little bit more, ie, the different qualities of different types of wood. A little bit like how different grapes make different wines. It was hard to find information on that, from the process of paper manufacture (as most seems to be pine) but I am sure there is an artisanal process of making paper from more exotic and rarer, non-farmed timbers.

If I do another version of this story, it will definitely be my next point of research.
