There is also a book called "Strictly Curls" that has step-by-step instructions on how to do curly styles. I don't have the book though, so I can't really give a review, but I've heard that there is only one or two styles for 3b hair and up.

You can also PM Amneris for ideas/instructions, who is the resident hairstylist queen. She's also read the Strictly Curls book, so you can ask her about it.
3b/c...or thereabouts.
