Twinkle little star

I did it! It took a couple of goes but I crocheted a granny star. And it even looks like the picture in the magazine. Now to bravely attempt changing wool colours, something I have always avoided for some reason... If anyone has any words of encouragement it would be appreciated. Its a bit like jumping off the high dive for the first time when you were a kid. I am sure its not that hard, but I always end up chickening out in the end...
