Does anyone know of any good free crochet patterns? I already know about crochet pattern central, lionbrand, and coats and clark. Any help is appreciated!

It's a single crochet then double, single, double, so on; so on... What is this called?

I love the stretchy headbands, but they always slip off my head after wearing it for five or ten minutes. Other than bobby pins (Not cute), how would you suggest keeping this bugger on? They are so cute, and I want to wear them, but can't seem to keep one on... is my head a stupid shape for them?...
