I don't think there's universal confidence in anything in life...
I dont particularly want a grimy rag that may have the virus on it from other people or my hand anywhere near my face so wont be wearing one.
I think part of the problem is that people may not know they have it and the idea is not to spread it to others, not to just protect yourself...
Look at the behaviour of people wearing them, they seem to think the other rules don't apply to them.
Haven't witnessed that. And I would view it as another simple measure we could take. And if we all got behind making homemade maybe it would create a sense of community.
