Now that experts suggest that wearing a mask or face covering is helpful against the coronavirus, folks are scrambling to make their own rather than tap into the supply of surgical face masks needed by essential workers.

This easy face-mask tutorial from DIY blog Japanese Creations has gone viral, and to make one, you don’t need to know how to sew or be even remotely crafty at all!

The site’s quickie how-to video has more than half a million views on YouTube. Noted entrepreneur Colin Hanks — whose parents, Tom Hanks and Rita Wilson, were among the first A-listers to contract the coronavirus — is a fan of the minimalist method, which uses only a square bandana, handkerchief or scarf (the bloggers use one that’s 18 inches by 18 inches) and two hair elastics.

What’s more, this method allows for easy washing: Simply toss the handkerchief in the wash when you’re done with it after each wear.

To make this easy DIY face mask even easier (not to mention more comfortable), use hair elastics that are slightly worn in, so they’re not too tight behind the ears, and pick a scarf made with a cotton blend rather than flimsy silk.

Here’s how to do it.
