@DoomsdaysCW @ai6yr Sorry I can't help with videos, but there are plenty of free, downloadable, out-of-copyright books on the Internet Archive on learning to sew on machines. If you have a borrowing account, you can check out newer books, as well.
The older books are actually better, because they address basic techniques that work on older/basic modern machines. I learned sewing before videos, so already have a collection of how-to books published between 1975 and 2000.
