Materials:
First, unfold the towel and place at the center the metal fastener that you put in place with 3 pieces of adhesive tape: one at the center and two others at the edges.
Fold up the towel around the metal fastener. Then fold it up again like an accordion in 8 parts of equal width, so that you obtain a band, about 2cm wide.
At each end of the band, place a rubber band and fold the paper over it on around 5 millimeters, then fix with another piece of adhesive tape.
Done!
You can then unfod the accordion carefully and place each rubber band around your ears
the metal fastener must be placed on your nose and you must indeed squash it on your nose
to reduce air leaks just below your eyes.
Recycling: normally, such a protective maks must be thrown to a trash after use. And indeed, the greay advantage of this mask is that it's so cheap that you won't hesitate to trash it. However, you can still retrieve the rubber bands and the fastener to recycle the paper towel in a dedicated trash (before that you should keep it untouched in some place during about 12h to ensure that most viral residues on the mask are naturally degraded). Then you can clean the rubber bands and the metal fastener with water and soap (you can also use some hydroalcoholic gel or bleach etc but water and soap are good enough, keep your hydroalcohol gel for situations when you don't have an easy access to water and soap).
