How to sew a face mask:
MATERIALS
Medical face mask template - https://www.marthastewart.com/1547458/medical-face-mask
Dense cotton fabric
Sewing machine and supplies
Elastic or cotton ribbon (optional)
STEPS
Download and print out template; cut out four pieces in total.
Rotate so that the top front of fabric shapes are touching. Sew two front sections on the reverse side of fabric—this will become the front exterior and interior seam of mask with a 1/4" seam allowance.
Cut the straps: top straps measuring 2 by 18 inches (tied over the ears) and bottom straps measuring 2 by 13 inches (tied at the neck). Iron in half so that two raw edges are touching; iron in half again. Pin the straps into the top and bottom of both sides between two finished pieces with seams facing out.
Begin sewing right under the top strap and stitch around the mask, ending right after the bottom strap on the same side where you started, leaving a 2-inch gap. Turn right side out. Leave space to insert a filter, if desired. Iron. Optional: Stitch around all of the edges again for added durability.
Optional: Elastic can be used instead of straps; simply modify the pattern to include a place to thread elastic, at the sides of the mask. Cotton ribbon can also be used in place of straps.
