For my first Little I just wrote down completely random, often contradictory things. For my second, I made the clues "ransom style"--cutting out individual letters and phrases and glueing them to things. I blatantly lied through my teeth the whole time so she would think it was someone else. It was really funny because this Little had been one of my best friends at school for the past 3 years, and she had no idea it was me.
