I've been playing the new beta a bit, and I was wondering whether it would make sense to allow creating cords from yarn, now that we have textilecraft? I modded the game myself to allow yarn to be used for standard cord, and renamed the old cord recipe to "Cloth cord" so that there is a source for cords in winter as well, because with the changes to clothing durability and the complete lack of wandering Njerps to rob in my part of the world, I have hardly any cloth I could sacrifice for cord - or bandages - and had to trade for clothes in a village just so that I could rip them apart for cords... I think this would be a good change to the gameplay, and would also give some more uses for yarn.
Also related: now that plant fibres can be used for making yarn, wouldn't it make sense to allow harvesting even picked plants, like nettles, for extracting the fibres? The leaves aren't used for that purpose, but currently, once you pick the leaves you can't do anything else to the plant.
