Note to self: Face Masks: a non-tutorial, just my notes

My iteration of a batik, pleated face mask. It is a cherry-picking of the many excellent tutorials on the web.  In particular,
https://www.providencelifeservices.com/resources/blog/providence-life-services/how-make-face-masks
was very helpful.

Begin by cutting 3 pieces of fabric together and layering them together. The 3 shown are 2 batiks and 1 Pelon mid-heavy interfacing. 
Next "face" the bottom and top layers using a single strip.

Then zigzag a pipe cleaner to the top seam allowance.

 Using the edge of the facing as a guide, add 3 pleats.

 Attach bias binding to the sides and close the resulting ties.
Viola! a mask.
