Halloween tombstone making class -- looking for help

We’re trying to put together a Halloween tombstone making class for a lead-in event to How-To-Halloween this year. It’ll be hosted at the makerspace and we’ll do some CNC carving of foam blocks and paint them up to look like stone.

I can handle the CNC machine part of it (although if someone else is itching to take this on, I’ll be more than happy to have help), but it’s the painting part that I think we could use an instructor for. Does anyone know anyone that can help out teaching that part of the class? Thinking someone with a props or scenic painting background would be ideal. @nlbroughton do you know of anyone that would enjoy teaching this workshop?
