We understand that not everybody has access to a sewing machine or a fabric store.  We have a design for an improvised mask that anybody can make out of a t-shirt; it would require only a t-shirt, scissors, a pencil, paper clips, a needle, and thread. You can find that here. While these would not be appropriate masks to donate to a facility, you would be able to use them when you go about daily, non-healthcare-related activities.
