@Magenta, I use Adobe Creative Suite apps mainly, but a few years back discovered Procreate which is amazing on iPad with the pencil. I use that mainly for sketching ideas, notes, etc, but occasionally for finished work. One of these days I will get around to making Scripture typography posters. Two ideas in the hopper are "Tetelestai", maybe in Greek characters, and "Via, Veritas, Vita", then with their verses integrated.
