it’s always a challenge to give numbers space, because you need to create a complete set where each figure takes up the same amount of room: The 1 has to be as wide as the 0 so that when you make tables they arrange. It’s just another design challenge. I don’t do a lot of designing or drawing myself anymore because there are people who are much quicker than I am, but the numbers I always do myself because I like them so much, even though I probably spend way more time than I should. They’re just too pretty.
