Easy way to make a face covering (2)

The CDC stresses the use of "face coverings" in its recommendation, not necessarily "face masks." So what's the difference?

A face covering can be any cloth that covers the nose and mouth, including a scarf or bandana wrapped aroung the face.

A face mask refers to a more specific shape that usually involves material that's more fitted to the nose, mouth and skull, as through the use of ear straps.
