There are a lot of people who don't know how to make masks, don't know where to get them and will have trouble finding them if needed. Dr. Denise Fair Chief Public Health Officer from Detroit shows a very simple way to make a mask. Its actually pretty simple and easy to do with a makeshift system. No cutting or strings involved. However, if you can sew a little (needle and string) you can make a better mask. You could also consider stuffing a pieces of cloth between the layers where the fabric line moves in the opposite direction to create better protection.
If you got to go get groceries or some other important business this is something you can do.
