Here is one that I’ve looked at, but not tried myself. https://jennifermaker.com/no-sew-face-mask-tshirt/?utm_medium=social&utm_source=grow.me&utm_campaign=grow_bookmarks
I was supposed to take a series of sewing classes March thru April of this year but Covid happened. I ended up pulling out a small “craft” sewing machine and doing Magpie’s pattern: Fastest, easiest fitted face mask pattern tutorial and it was super easy. Especially if you can work out a system of doing all of the same steps at one time and go through each process. I did take some shortcuts through it based on my abilities. The ones I’ve done have held up pretty well.
