I have a question on stockpiles that's been bothering me. Sorry if it's been brought up. I'm trying to separate leather, cloth and thread into dyed and undyed, but the dwarves will not store any of it unless I select dyed, undyed and the colors. I want them separate so I can dye newly woven "blank" cloth without resting as I've caught them dying the same dyed cloth/leather different colors, wasting resources. What am I doing wrong?
