People around the world are apparently making masks for medical staff. Although it would obviously be better if a health service was funded sufficiently in the first place this real effort to help is a very positive move and gives me some hope that there may be more good people out there than the ones who have stripped the supermarkets bare.
(Oh wow! A kingfisher just landed and sat less than six feet for a while away as I was writing this.)
I belong to several sewing groups online and have accounts with several fabric retailers so I know what's going on. There are literally hundreds of not just individuals but whole sewing groups around the world who have given up their normal projects to make masks and my local quilt fabric shop has donated whole rolls of fabric to one local group. There are any number of free patterns online. And anything that can be made on a sewing machine can be made by hand as long as you can sew.
