My fictional world is based on a critical point that happened in the past: Magic, which beforehand had been used in everything, suddenly stopped working. Up to this point my world had been a sci-fi/technology-advanced world. Magic suddenly stops working, and everything breaks. Thus technology-wise the world is thrown back to non-magical means (which I envision as being the typical medieval fantasy world), though the knowledge of having more advanced stuff still exists (though probably a lot of it was lost, since if it was stored in something that used magic -- and everything pretty much did -- it crashed).
- How long would it take to reinvent modern technology using a different power source?
I'm hoping for a few centuries, considering our own history (medieval to the 2000s), but this was when we didn't know what was possible. For a very stretched example, it's like as if electricity and combustion in our world suddenly stopped working, but photosynthesis still did, and some guy wants to recreate the iPhone using photosynthesis.

I really have no idea how to search this, since it's more theoretical. I tried "information technology history", "invention history" and permutations of that but that gave, well, history, and it doesn't really fit what's happening in my fictional universe.
- Can denim be manufactured by hand, or by very simple machinery?
I keep envisioning my main character in loose jeans for some reason. Because of the aforementioned magical crash, the previous methods of manufacturing don't work anymore -- so I'm trying to figure out how the cloth can be made by hand, or the simplest machinery that will do it feasibly.
Search terms: denim, denim manufacturing made by hand textile, "how is denim made", "cotton twill textile hand" <-- I learned about the weave, and stuff on how jeans are hand-made, but not on how/if the cloth itself is made by hand...
