I've found after some rifling through random materials at hobby lobby, co-op, and home depot, that mosquito netting is optimal for this preventative device. It is very fine, which is necessary to keep the virus out of a person's respiratory system, but most importantly it is very soft and easy to maneuver, which is obviously the most important aspect of this mask. I want whoever that is to wear this mask to notice two things: one, that THEY don't notice that they're wearing it and two, that NOBODY else notices that they're wearing it. Invisible prevention.
