Crochet novice

I decided that I would learn to crochet this summer as I would quite like to have a go at some cotton crochet toys. Between You Tube and Mags, I have been trying to develop my skills. Tonight I tried to replicate a granny square which Mags tutored me through last night, however, I seem to have created a hexagon tonight!!!
Apparently I've lost my corners....if anyone finds them could you send them to me ;)
