Like when Billy Connolly said "who discovered milk came from cows, and what were they doing at the time ?" You have to wonder how the first human came up with the method for getting fibre from the flax plant. It's a multiple step process that requires days to do. And then it all needs to be spun before it can be Woven.
For millennia spinning was done with a tool called a drop spindle. It was slow, and repetitive, and it took a lot of time to make the thread for a simple garment.
