How do people stencil on a tiered cake?

How to make a stencil of the pattern I want?
If I want a white background and black stenciling what types of icing do I use? Can I do buttercreams? Can I use a buttercream base and overlay it with royal icing stenciling?

Any links or videos are helpful!

I've been wanting to try stenciling but didn't know where to start.
