We're putting together some low-fi prototypes in Sketch for some new FarmLogs concept work today. We've used Helvetica in the past for low-fidelity, but I want to try a typeface that makes it obvious our mockups are NOT the final type/spacing etc--without making them hard to read. Comic Sans is working pretty well actually (I know, I know).
What type/font do you use for low-fi?
EDIT: Thanks for not crucifying me for suggesting Comic Sans y'all
