All those months ago, I begrudgingly bought enough washable masks for the family to have a supply each. My aim at the time was to do it as cheaply as possible. If I'd realised how long we'd be wearing them I'd have invested in some pretty ones for myself 
Resigning myself now to wearing them a lot over the Christmas festivities (and clinging on to the hope that they will actually happen) where's a good place to look for a "nice" one?
