In the process of improving this guide, pictures/videos of different copies of the mouthpiece / facemask have been taken, therefore there are differences in thread color, background and little difference in the pattern. The dimensions of the pattern are all the same.

Sew / stitch 3-4 mm from the fold so that there is some stiffness in the fold.
