It is needed to ask An_dz for dat and png file of Arboria. I have only playable files - and original sources.
I hope that soon I will have idea for tailor - and later for factory that will be producing wool. But whole chain would be playable after making tailor.
Other textile fibres (wool, cotton, hemp, nettle or so) are only for higher level of complexity and making chain more interesting. And that I made that chain quite interesting with using of flax for main process material - instead of cotton.
At this time I have only idea for historical version of textile factory - and few next factories (at least one - open coal mine).
