An experiment — took a pleated, 2-ply cloth Old Navy mask that I had from the earliest days of this pandemic, draped it over the Dentec Nx facepiece, and applied a fabric stiffener mixture of Mod Podge and water. I wanted to see what cuts and shaping would need to be done without wasting good fabric. I let it sit on the facepiece for a few hours to see if it would take the shape, then carefully moved it to let it air dry for ~10 hours.
