It can be done. I did it yesterday. I made pasta by hand, with only flour, salt, eggs, a rolling pin and a knife. It helps to have some very strong arms (the pasta that Todd, taking pity on my, rolled out turned out much better than my too-thick pasta). The dough started to get kind of rubbery toward the end of the rolling, and would contract back after every roll. I think letting it rest for a few minutes helped, but it would have been even better if I were a more patient and persistant person.

I think I've decided to go ahead and get a hand-cranked pasta machine, since they don't seem to take up that much space. Homemade pasta is so different from anything else, and it'd be so easy with a machine. I have a little bit of pasta dough left, and I think I'm going to experiment with some other shapes for my dinner tomorrow (I made ravioli yesterday).
