Nearly every machine threads the exact same(with the exception of overlockers/sergers) so once you figure out one machine it will be the same. I've got six machines in my dungeon, while one is an overlocker, the other five are all different ages, models, types, but they allllllllll thread the same. If your mom is okay with it you can take a fine tip sharpie and draw the path on the machines, along with 'clues' to remember what to do at each point. I was lucky that the first machine I ever learned on(well, really learned, my mother sucked at that) had a good diagram already on it. And my serger has a really detailed one too since I have to re-thread the darn thing all the time.

I was having a convo yesterday and realized that in a couple years sewing and all that may as well die out, it's not being taught any more. Which IMO is super sad, why aren't we seeking to learn this any more, are we just assuming it's not a necessary skill? My friend joked it was because you can't grade it with standardized testing, and sadly she's probably right.
