Fabric (100% cotton is most effective)
Sewing machine or a needle and thread
- Measure and cut two pieces of fabric in a rectangle pattern to fit snugly around the face (size 12 inches by 6 inches is standard for adults).
- Tightly sew both layers together on all edges.
- Cut fabric ties to fit around the ears.
- Sew the ties to the insides of the mask on the smaller edge, repeat on both sides.
- Resew the sides to ensure a tight seal between both pieces of fabric and the earpiece.
