There were more steps than I mentioned of course, but I can't give Donna's class away, now can I? I did conclude that for right now, PMC is not really for me. The expense of the clay, and the amount of time required sanding, makes it seem almost impossible to get into. Perhaps as you get more experienced, the sanding time goes down, and I am sure copper clay has to be less expensive, but for now, I'll just admire things other people make with PMC.
Here's an example of Donna's art, which you can see on her web site.
