You can read some of O Street's answers in our Storify below. And if you like what O Street have to say, you can hear more from them at the Craft Scotland Conference on Friday 7 October 2016, in Dundee.
For their Conference talk, David Freer and Ed Watt will be talking about their latest project, Roadliners, a film all about the uncelebrated typographers of the road, craftsmanship and inspiration. The film is so good, it brought a Glaswegian roadliner to joyful tears. Their talk will touch on the inspiration behind O Street's recent re-branding and how to go about making a typeface.
