Hello - i'm stuck in CA. the politburo here has graciously allowed gyms to reopen, but muzzles are required and valve masks have been banned for being too comfortable. i'm going to order some single-layer gauze masks off of etsy, but does anyone have any recommendations on how i can conceal the valve holes on a valve mask? (maybe by removing the valve and sewing a thin layer of gauze over it?) Has anyone used neck gaiters and cut vents in them?
