I tried to make masks of several styles and now I think this one is the best. Also it is very easy and quick to make. Then if you wear glasses, it will definitely fog much less. Here I show “Size M”. For the other sizes, please check the bottom of this page.

Draw the pattern as shown on your usual printing paper. Cut it. Then place it over the fabric and cut the fabric.

Fold both cuts in half and iron press them in the center.

Put them together face to face matching the center point. Then sew with 0.7cm seam allowance (the green dotted line).

Turn the mask and do the same for the opposite edge. Sew with 0.7cm seam allowance (the black dotted line).

Now both edges are done.

Turn the right sides out, and iron press along the top and bottom edges. Make sure to leave a gap of about 1mm so that “liner” does not show when looking from the front side.

Fold along the center line and cut off the corners. The green arrows show you where to cut, along the white lines. They are also drawn on the patterns for the other sizes at the end of this post.

Unfold and sew the top edge (with 7mm seam allowance) and bottom edge (with 1 to 2 mm seam allowance) as shown. As per the green dotted line.

If you have “nose wires”, it is time to use them now.

Insert a “nose wire” from the side in the space left by the 0.7mm allowance along the top edge, as shown with the green arrow. Feed it inside the space and place it at the center.

Once the nose wire is placed in the center, sew the sides at each end (the green lines, indicated by the arrows) with small stitches (i do #1). It will prevent the nose wire from moving.

Fold 4cm from the bottom and iron press.

Fold 5cm from the top and iron press.

Turn the mask to the other side and sew top and bottom with 1 to 2 mm seam allowance (along the green dotted line).

Turn to the other side again, fold out the top and bottom as shown. Mark 4 points on the right side of the outside mask, on the first fold line. Where red dots are indicated by the green arrows. Use a water soluble sewing pencil.

Now mark 4 other spots 1cm from the edge (top side) and 2cm from the edge (bottom side). This time they are on the liner fabric edge, as shown (the red dots below).

Match the marks together and clip the fabric in position.

Cut off the parts (right and left) outlined in green. Be careful not to cut into the front layer of the outer mask. The picture below shows the mask after cutting.

The below shows the result.

Then fold right and left outer mask to reach the liner (until green line). Then iron press :

Fold again to the place where you marked the spots and clip together (both sides).

Sew along the green line on both sides with 1 to 2 mm allowance. We’re almost done…

View from the other side :

Insert the elastic rope on both sides.

Tie up the rope taking your size into account :

Then move the rope loop so as to hide the knot inside the outer mask side fold :

Done :)

You can easily draw the pattern on a piece of paper using the following guidelines for the other sizes :
