This a very professional-looking mask, made without a pattern.
Thismask video tutorial by Crafty Daily on Youtubehas great instructions that make this mask so easy.
The mask has a double thickness and a filter pocket inside.

Both sides of the entire mask are pleated and ironed before you sew any of it.
This ironing method makes it really easy to see exactly what you are doing.
This is one of the best mask tutorials Ive seen.
