How to sew your own face mask.
Here are Miss Williams' instructions to make your own face mask. It is very easy and they can be handsewn if you don't have a machine.
Here are the instructions to make a filter. Ensure you use a non-woven fabric, such as a J-cloth.
The mask is washable but please dispose of the filter after a days use or equivalent.

Please note that these kind of masks are not intended to protect the wearer, but to protect against unintended transmission, in case you are an asymptomatic carrier of the coronavirus. This of course does not replace the proven precautions like self-quarantine at home, social distancing and thoroughly washing your hands.
Stay safe everyone!
