I'm about to start a project designing several large information/interpretation panels, and i've never done this sort of large scale design before.
Each panel will be around 4ft wide x 8ft tall
with around 200 words of text and a couple of images.
I have to use the client's proprietary typeface (which is similar to Optima)
Any tips? Anything I should avoid as far as letter or line spacing? (beyond normal things like orphans, widows etc.)
