Teaching Watercolor

Ah watercolor--the bane of my existence some days. Every year, when I teach my kids to use watercolor, the paints inevitably become muddied and quickly wasted in the form of thick opaque globs and strokes in my students' artwork.  As I don't want to go through all my refills by Thanksgiving this year, I feel I need a new strategy, which is where this week's lesson comes in.  (After blatantly stealing the idea from Other Art Teacher) I am reteaching watercolor procedures to my older kids and swapping instructions for the younger ones.
