Pinky cupcakes

I spent more than a  week baking cupcakes, FIMO cupcakes. They seem so delightful and so easy to make when I see them on other blogs, made by artisans. But the truth is that it's very difficult to make something round and creamy looking like an actual cupcake. First the pastry is too yellow or too white, then the paper lining is not pleated but wrinkled, and the cream is collapsing. Eventually, I have some white and pink cupcakes for my display !
