A news release from Gov. Tim Walz shared that the following face mask design patterns and instructions can be found online and below:
Build a mask that tightly encloses the area around the nose and mouth, from the bridge of the nose down to the chin, and extending onto the cheek beyond the corners of the mouth, so no gaps occur when talking or moving.
Use mask material that is tightly woven but breathable. Double-layer the fabric if possible.
Masks must be made from washable material such as fabric. Choose a fabric that can handle high temperatures and bleach without shrinking or otherwise deforming.
The mask should be tolerant of expected amounts of moisture from breathing.
Outer layer tea cloth.
Inner layer of a microfleece to wick away moisture.
Use an accordion fold to mimic a hospital mask as much as possible.
Use a fat woven shoelace type material to bind the sides (such as quilt binding).
For straps, use elastic straps that loop behind the ears.
The Centers for Disease Control recommends wearing cloth face coverings to protect others from COVID-19. Cloth face masks can help prevent the wearer from infecting others - especially in situations where they may spread the virus without symptoms.
Cloth face masks are not a proven way to prevent COVID-19 from infecting the wearer.
