Here's a face mask pattern for you...it could be done as a Crazy Quilt version if you like...but be careful to secure everything well if you plan on putting it into the washing machine.

The size is adult or young adult and covers the nose/chin both. I used about 8" of elastic (made a circle after threading it through the sides) but it is best to test out your length for each individual person.

The shape reminds me of a bra cup...okay, my silly sense of humor...but that might work too! Ha!
Bet it would get loads of looks as well. ;)
