I made a dozen good homemade masks in a few hours, and I am inept at sewing. With some practice I could make 200 a day. There's no point to doing so, it would be illegal for me to sell them. US is doing nothing whatsoever to ramp up mask or ventilator production. It's going to result in a lot of deaths.
Please share a pattern or document how you did this, I'd be very interested in making some for people around me.
The Hong Kong kind is simple enough (and it also suggests a transparent shield):
