How do I get naturally wavy hair without using harsh products?

My hair is quite short, probably about 7cm under my jaw (when it hasn't been straightened). I want to have natural looking curls that look kind of like these (but with shorter hair, of course):

I have hair curlers, a straightener,a hair dryer, elastics, booby pins....not much else....

Anyway, does anyone know anyway to make my hair like that (or at least, similar?) Also, I don't want it to make my hair look any shorter then a bob.



Thanks!



P.S. pictures of how my hair might turn out if I do what your answer says (just copy and paste the link) would be nice!How do I get naturally wavy hair without using harsh products?
Put your hair into a few loose braids when it's damp. Fasten the braids with elastics. Let your hair dry naturally. Take off the elastics and take the braids out. Then run a comb through your hair a few times so it doesn't get tangled. Your hair should be wavy after this, no harsh products required.
