Hemp or Wool > Loom > Makes reel > Reel to cloth > smash cloth up with grinder > get rags > rags in press > makes paper > make poster > sell on eBay (other online marketplaces available)
As I said before, the unity version doesn't have Loom... But the following sequence worked...
Wool > Yarn > Coarse Cloth > Rags > Paper
Wool in Spinning Wheel = Yarn
Yarn in Workbench = Coarse Cloth
Coarse Cloth in Grinder = Rags
Rags in Paper Press = Paper
Thanks for the grinder tip, that was the missing point and killed the charade =P... In the videos I found about the old version (non-unity), it involved putting water in the press with a bucket, but there is no bucket in the unity version and watering can doesn't seem to do anything at the moment.
