So at 1M how big do people need to work to have a realistic chance of getting their "thing" to be legible?
I think that anything needs to be at least 30M on each side and in high contrast (black or dark blue )to make a recognizable image, but if they hope to move an audience to tears... bigger. Much bigger.
How big for a plain ol' "HI MOM"?
If we give artists reasonable boundaries and expectations, they can't bitch about the results afterwards.
