Woven cotton has some pros but also cons. It’s easy washable at a high temperature and it’s comfortable against your skin. Cotton doesn’t keep out the viruses very well, I read. Cotton soaks up humidity from your breath, which is not good ‘virus wise’. Polyester and polypropylene are denser, so they keep out viruses better, and don’t soak up humidity as much as cotton. But they are more difficult to work with and people don’t tend to have this material in their stash.

Non-woven material appears to be better than woven material, according to this article. They compared different materials and criteria and concluded that the fabric that is used for a cotton t-shirt is the best option. So, you can start cutting up old t-shirts!



However, most governments are insisting on using woven cotton. And I can also confirm that woven cotton is definitely easiest to sew.
