I can't really advise you on what classes to take, but I can in turn ask you these questions that might help you decide. What are you planning to do with the work you make? sell, give away or keep for yourself. How much money do I have to invest if I get hooked on the new technique. With the pmc there are some key tools that you will need to have to finish, like either a torch or kiln, burnishing tools, etc. When it also comes to expenses the pmc is also expensive to work with. Just my thoughts. I do play with pmc but I already had a kiln and most of the tools to work with it, so I wasn't faced with a lot of extraordinary expenses. I have used resin products for other things then jewelry and have a stash of that in my workshop too. If I can help anymore, just ask.
