Fred Mullett Anyone?

Here's a couple cards that I made during a class I taught last Saturday.  The techniques are inspired by Fred Mullett's stamps and the classes he has posted about on this website, which you can find here.  I stamped the image above and embossed it using two different colors of embossing powder (silver and black).  I then applied some washes of acrylic paint.

This card also uses a Fred Mullett stamp, embossed with a variety of different colors of embossing powder.  Since it's all sparkly and shiny, it looks much better in real life.  Fred calls this technique "painting with embossing powders."  Tim Holtz also used this technique for one of his 2008 Christmas tags, which you can find here.
I have never taken a class with Fred Mullett, but I sure would like to.  I admire how he takes stamping  to a different level and turns it into mixed media work. Have any of you ever taken a class with Fred Mullett? If so, what did you think?  Is there any other teacher who you would like to take a class from?
