Making Taco Shells from Scratch?

I'm ready in a quandary here. I was making tacos at home. I didn't have any of the tortilla shells (soft) so I decided to make my own; big mistake! Or I screwed up, somehow. I was using the masa flour and I mixed it like it said to. I couldn't roll them out of make a tortilla shell. About the only thing I could do was to deep fry them. They were better that way, but they were still not up to par. Can anyone give me some advice on how to be good at making them? I sure would appreciate it.
