I've just finished taking Roben Marie Smith's Mixed Media Mayhem online class.  We made a "journal" out of utilitarian file folders.  Spray inks, stencils and gesso was about all the supply list consisted of...oh, yes, water.  Lots of water.  I really enjoyed exploring these techniques and was amazed at the tremendous possibilities and results.  Lots of spontaneous creating which is good for the soul.  Here are some pics of my finished, hand sewn journal.
