Same here.. It's been a problem figuring it out for me, since my hair used to be only wavy on top, and "sausage curls"...corkscrews at the ends and underneath. You probably could benefit from using products that both 3a's and 3b's love, which I do! My hair is now sort of a mix of different sized curls like you describe... In the CG book, my hair is like a cross between Keri Russell's and Nicole Kidman's, and as a result, I generally consider myself to be 3a corkicelli

A picture would be great!...Or you can click on the orange CurlPix button at the top, and find a picture that is similar to your hair

Hope that helps!
