In premodern times, in temperate or colder climates, clothing was orders of magnitude more expensive than today and textile production made up a large percentage of total economic activity. I'm interested in getting a feel for the actual numbers involved.
To take something concrete: in the Middle Ages, how many hours of labor did it take to make a woolen sweater?
But I don't mean starting with a ball of wool. I mean starting with a sheep. I'm interested in the total labor cost.
As I understand it, there were several steps: shearing the sheep, cleaning the wool, spinning it into thread, then weaving or knitting the thread into clothing, but they were not equally time-consuming; spinning thread, took considerably more time than all the other steps put together.
The spinning wheel improved things significantly, but the Middle Ages was before that, when distaff and spindle were the relevant tools. (And as I understand it, would have been substantially unchanged since at least the Bronze Age.)
A good starting point, then, would be if there are figures available for how long it took to spin a certain amount of thread with distaff and spindle, given an experienced worker.
