Saw the doctor a few days back who said that you could make an effective mask using four layers of sweatshirt material. Regular towels have too coarse a weave, and she was unimpressed with my suggestion of shop towels.
Four layers of sweatshirt is a bit heavy for a mask, but since lots of us wear baseball caps anyway, a VAF cap (or equivalent) can provide a force in the Nz direction, or, if you prefer, lift vector. I made a kind of cowboy mask that attached to the cap and then safety pinned the four layers of sweatshirt material to the front of it. There are any number of ways to pull the mask back towards your face (increased drag vector), depending upon what you've got on hand and how you implement the mask.
Ugly, clunky, cumbersome but a small price to pay.
Be safe, be well, wash your hands.
