There are a lot of hospitals directing employees to sew them by hand.

There is a simple and reliably repeatable method: having a factory. Not sure what is needed but there are lots of suppliers on Alibaba for this type of item. There are lots of rumors about export controls in China, denials of the same from Chinese officials, and rumors of seizure by US customs.

Never imported medical stuff but anecdotally many US sellers are being solicited by Chinese factories looking to sell masks and other PPE into the US.
