This non-woven, sew-in interfacing is great to be used as a filter layer in a face mask. One 58" x 18" piece will make 12 mask filters. It can be sewn between the exterior and lining of the mask, and can be machine washed.
Watch our video tutorials on mask making to see how we use this in our sewn masks.
