I'm irked every time I go into a store, as one of the few non-mask-wearers, that I'm not using a wise T-shirt to try to awaken my fellow shoppers.
Irked enough that I want to design/print one/some but don't want to get too obsessed with this "hopefully going to fade sooner rather than later" phenomenon. Heck, I look at some of the shirt-delivery times and wonder if the fraud will be revealed before I get the shirts (probably wishful thinking).
I'm not looking to reinvent the wheel, so does anyone know of any existing shirts/sources?
