We are a team of academics, physicians, trainees, people who sew, and other volunteers.  We've been working on identifying published, peer-reviewed literature to inform the choice of materials and designs for cloth masks, communicating around materials and design, and curating high-quality information on mask use and mask cleaning.

At present, this site and all our work is on a voluntary basis, without funding.

Our academic work includes an opinion piece available here and a narrative review available here. Our plain language summary is available here.

Let's redouble our efforts in every other area as children go back to school. Catherine Clase and Zain Chagla discuss Back to School Best Practices with Mike Rosen at Rediscovering Play.
