Got some cotton ones from the mother in law and am wearing them as the science has now said there seems to be a little evidence about them slowing the spread. The ones she made are cotton with Velcro and I'm in and out of hospital at the moment with antenatal appts. But god,I wore it today and it was hotter than hell and felt like I couldn't breathe. Could anyone point me in the direction of any they bought on Etsy or anywhere? Not interested in surgical masks as am not buying any that front line workers should have.
