This is simply a cover that hopefully will prolong the usability of the N95 respirators.
Lay fabric right sides together. Cut 2 from fun fabric, 2 from liner fabric. Sew on sewing line. Clip seam allowances where you see notches. Layer masks facing right sides together. Add four 18" ties to the spots marked X, making sure the ties lie INSIDE the masks. Pin the two layers together, then sew, leaving a small opening on the bottom for turning. Turn mask, pin opening shut and sew a small seam all around the mask
