What are you going to use for your stencil? Royal icing is white when you make it, no coloring is necessary.
They do look wesome.
I'm going to be making my own stencil

what i want to know is if you piped the royal ising on or is you painted it, and if you piped it, how did you fice the stencil to the cake?
I just did a couple stenciled cakes (they are in my album on here) They were black fondant with white royal icing stenciled on and it was wonderful... super easy to do too! Got the stencils from Global Sugar Arts.
