I sincerely hope not. I think my local pharmacist is thinking about early retirement because he is charging £3 a face mask and let's face it, they are disposable after each time it is used.
I am quite looking forward to it. I have raided my stash and made myself some masks from really pretty floral material with lace and ribbon trim. I have several, they are easily washed and ironed with a really hot iron.
Patterns are readily available online and they can easily be made by hand. You do not need a sewing machine.
I have some, DD is a therapist, is unable to work at the moment and has some spare ones, if I go shopping I will certainly wear one, whether or not we are advised to.
