Back in the day (82 or so) I didn't know where pre-made character sheets came from; probably I saw some that older kids at the library group had, but the idea that you could buy them (e.g. the goldenrod AD&D ones) either never occurred to me or seemed too expensive. So I sat down with a typewriter and laid out my own, by the expedient of going across each row, typing in the things I wanted on that row, and then putting in a : where I wanted a vertical line between sections to appear, then doing it again on the next row with the : hopefully lining up with the one above. How much time and White-Out I spent on this cannot be imagined. (I did then have my dad copy it at his office, though - I didn't do it every time I wanted to make a new character).
