Watercolor collage

Several weeks ago, Wendy at Stampadoodle did a demo on watercolor collage. I've been playing around with the technique since... and thought I'd share a couple of artist trading cards I've created. These use watercolors and stencils, with some sketching.  Mushrooms!

This one is in process - I need to add the sketch details. 

These all started from this master sheet, which I cut into the ATC backgrounds.
