And after you use it, simply throw it in the washing machine.

We found this tutorial for a pleated face mask from the website Japanese Creations. You only need a handkerchief and two elastic hair ties to make it, although you could use a cotton T-shirt or other materials and follow the same steps. If you don’t have hair ties, any material that could be fashioned into a loop that would hook around your ears could work.

We used a bandanna; the standard size is about 20 inches by 20 inches. You may be wondering, “Why not just tie it around your face, train robber-style?” The goal is to get as much material layered in front of your nose and mouth as possible.

Step one: Turn the bandanna face-down and fold one half toward the center.

Step two: Fold the other half in toward the center.

Step three: Flip the bandanna over so it’s face-up.

Step four: Fold one half toward the center.

Step five: Fold the other half toward the center.

Step six: Flip the bandanna over again and slide an elastic hair tie on each end.

Step seven: Fold the ends in toward the center.

Step eight: Flip the mask over. This is how it should look.

Step nine: Pull the elastic hair ties to the sides and slide them around your ears. Voila! A pleated face mask.
