Designing a typeface is an enormous amount of work, which usually starts out by hand. I worked on a typeface in art college but have never gotten past the sketching stage. I'd love to show you my sketches one day, but I'm afraid they're lost in the attic.
I've done a quick Google search for hand sketches and here are the results. If you're interested in the proces of type design start reading I love typography, where I found most of these images.
