Prewash all fabric in hot water before cutting!

These should be washed between each use, and prewashing will minimize fabric shrinkage.

Suitable fabrics include tightly-woven cotton, such as quilting fabric or bedsheets. Flannel is nice for the lining, but not required. 

Use two different fabrics so the wearer can avoid putting the potentially contaminated side back against their face.

Cut the following:

  • 1 piece cotton woven (7" x 9") – be sure any directional fabric is cut horizontally.

  • 2 pieces cotton flannel (4" x 9")

  • 2 pieces elastic (7" long) – use round cord elastic or 1/8" – 1/4" flat elastic.
    For round cord elastic, tie a small knot at each end.
    Do not tie a knot in the flat elastic.

  • 4 ties (18" long)
    Use ribbon, shoelaces, twill or bias tape, or sew fabric into long tubes.


1.  Sew the long edges of the flannel, right sides together, at a ½" seam allowance. Leave a 3-4" segment in the middle unstitched.

2.  Press the seam over to one side.

This will allow for a self-closing pocket in the lining.

3.  Attach the elastic (or ties) at the corners on the right side of the cotton piece (loops inward).

4.  Lay the flannel on top of the cotton woven and elastic, right sides together.

5.  Stitch around all four edges using a ¼" seam allowance.

6.  Clip corners and turn right side out through the opening in the flannel.

7.  Your mask should look like this at this point:

8.  Press well.

9.  Press two pleats into the mask – both should go the same direction.

10.  After pressing, pin pleats into place.

11.  Top stitch around the entire edge of the mask twice, ensuring the pleats are flat while you sew.
