I am in favour of homemade masks.
An article in the Economist (can't be fucked to find the link right now) referred to a study claiming that a layer of t-shirt fabric in front of your face reduces the amount of particles you expel into the air by 50%. Lifted to a societal level this number obviously needs be revisioned downwards by factors such as not everyone bothering to wear them, people wearing them improperly etc..
But let's say we end up with and estimate suggesting that widespread use of homemade fabric masks will reduce the infection rate between strangers by ca 10%, surely that makes it worthwhile as we ride out the crisis? We're cyclists. We love a bit of marginal gains don't we?
