Help with crocheting flowers please?

Hi guys, I'm not too bad at crocheting, i can do bags, throws, shrugs etc and the results are doing well, but i am having issues finding easy to do flowers. I have tried before, but am having problems understanding the magic ring/ crochet round your finger method. Also having issues with decresing stiches to make and heads for soft toys. Any know of any website, preferably with videos, but doesn't matter too much, that can help me? Thanks guys. x
