Jenny and I went to an Art Journaling class at The Creative Quest a couple of weeks ago and had a BLAST!  It is so much fun.  You put some gesso down as a base on some watercolor paper, let it dry, then attack it with acrylic paints, stencils, spray inks, oil pastels, and Sharpie pen journaling to finish.  It was so relaxing and is theraputic in a way because you can make it be anything you want!  No rules at all.  And if you "mess up", just say "I MEANT to do that."  (Like Pee Wee Herman...)
