It started, like most bad ideas, in the supermarket card aisle at 9.30pm the night before someone's birthday.
Row after row of the same stuff: beige flowers, dad jokes from 1998, "To a very special friend" in curly gold font. Nothing that sounded like anything my mates would actually say.
So I went home, messed about with my own designs, got a few printed, and people started asking where I'd bought them.
I hadn't. So I decided to.
