Thanks indydebi. I will have to try that! I had been fairly successful with the flower nail until recently. I just realized that my latest problems have been since I switched to using a cake release that has a lot of flour in it! (I had thought it was the new cake recipes I had been trying, but then it happened on one of my tried-and-true recipes). I will try just greasing the flower nail and see how that works.
Time to bake a cake!
