Those cloth face masks that you made from recycled old clothing and materials...
That's a great way of recycling - and very useful in helping to conserve the limited supplies of surgical-grade masks for the medical professions - who are the one's who really need them.
You should make more of those things! (And don't forget to upload some photos of the finished product.)
Cloth masks will not protect you against air-born viruses but what they will do, is that they WILL be a massive help in reducing the transmission of viruses among the population. Basically, if you sneeze or cough, they really help to protect the people around you.
Social responsibility! Recycling pa! That is one of the reasons - among many others - why the spread of Covid-19 has been relatively well-controlled in several South East Asian countries... Places like Japan, to name just one, where people are used to wearing masks when they are not feeling well and they have to go out into a public place.
It's just being sociably responsible to the people around you.
