Do you have any candy melts that you can color black. I made a cake with a Mickey Mouse hat on top of it. I melted the candy melts and made a circle with a point coming off one side. I cut a slit into the top sides of the hat and slide the pointy side into the cake. I thought it turned out cute plus it was easy. There is a picture in my gallery. Just thought I would give you a different direction to go in since the painting isn't going well. Good luck.
