A second pattern for face masks from a friend: https://www.instructables.com/id/DIY-Cloth-Face-Mask/   Use mask 1 pattern with filter pocket. This pattern is what a pulmonologist from Barnes Jewish Hospital (St Louis) sent to me.If any of your email friends are quilters, they will have lots of 100% cotton on hand.
