This is a pattern with instructions for an ergonomic face mask with a protusion for fitting well over the nose even without a clip and another protusion for fitting under the chin as well.

It can be made single- or double-layered. I use double-layer for interior spaces where aerosols can accumulate easier. When walking, cycling, ... outside I use a single-layered mask as aerosols are less of a problem outside and it's easier to breathe. Optionally, you can equip a double-layered mask with a nose clip. I use simple aluminium flat wire (as aluminium doesn't rust), but anything bendable should work.

I designed this back when home-made cloth masks were used, which is what got me into sewing.

The pattern consinsts of hand-crafted (because I'm weird) SVG vector files. Run `make` to generate printable PDFs. Take care to print using original scale.

1. Print out the patterns in original size.
1. Cut out two outer pieces from your fabric.
1. Lay the pieces on top of each other, outside on outside
1. Sew the long curved sides together about 5 mm from the edge, optimally using an overlock stitch to prevent fringing.
1. *(For single-layered masks)* Hem the upper and lower edges by folding about 3 mm of the fabric edge over to the inner side twice and securing that hem using a simple straight stitch.

    *(For double-layered masks)*
    1. Cut out two inner pieces.
    1. Hem the short straight edges.
    1. Lay them on top of each other, inside on inside.
    1. Sew the long curved sides together.
    1. Pin or clip the outside and inside pieces together, outside on outside, nose curve on nose curve.
    1. Sew together the upper and lower edges, again optimally using an overlock stitch.
    1. Turn inside-out so it is oriented correctly and carefully press.
1. For both short sides: fold in about 3 mm of fabric as hem, then fold about 1,5 cm and sew over the hem. That should leave a tunnel of fabric.
1. Channel elastic band (about 22cm depending on the elasticity and your head size) through the tubes, knot the ends together and push the knots into the tunnel.
