I think you have gorgeous hair. I guess you'd be a 2c, if you say so..I am a 2c also but the very ends and tips of mine are straighter (I did permanently straighten mine about a year and a half ago though so the entire bottom half of my hair is straightened and still gets some waves.) But the ends of yours look like real curls to me. (so at least some 3a?) I hope eventually my ends will curl like that, maybe after my haircut today.
We'll have to post more pics after we have done CG for a few months. Best of luck to you, but it looks great right now!
2c thick, heavy waves. Started CG (lo poo) in July '07. before that I straightened it and used hot rollers for years. pw wavy
