For example before you could do this you would need to have learned how to make cloth to make the bag.
Before you could make the cloth you would need to know how to weave.
Before that you would need to know how to spin so you would have something to weave.
It is really interesting how everything we do is dependent on having something that came before.
It’s remarkable how the amount of labor to make garments has dropped, and how the resulting free time has turned so many of us into couch potatoes. :^) I was looking at a spinning wheel (donated by a cousin to a museum) from at least the 1840s and considered, at least one of these used to be in every home.
