A Crafty Crochet Cloth

This is my first crochet project. The yarn I was given in class wasn't enough for a dishcloth, so I bought another cotton yarn. I've torn it out several times, and will be working on tension for a while, I'm sure. It's a satisfying sort of craft, and a dishcloth is fairly mindless, which is good sometimes. I'm not sure what's next, once I get the dishcloth finished. I did buy a soft, bamboo blend yarn with thoughts of making an ear warmer. And I've begun thinking about making a small rug for the bathroom, out of cloth scraps. I've got lots to learn first, and would love any suggestions on books, yarn sources, etc.
