Fold the mask in half, aligning the two bottom corners with each other.
The mask should be inside-out, so that the inside of the mask (lighter fabric, if applicable) is facing out.
You can pin the mask together if you want, but it was stiff enough that I didn't need to.
Carefully sew the center seam, running from the bottom corner to the upper straight line.
Stop and adjust your angle at the halfway point to follow the mask's contour.
Sew roughly 1/4" (6 mm) from the edge.
Stop at the point where the upper straight line meets the edge of the mask. See the orange arrow in the photo for reference.
