I like to show the students examples of stained glass (I use a Tiffany book) before I introduce them to this watercolor project. They get to see complex subjects broken down to simple shapes. The glass has many colors and direction in each piece that together makes an interesting whole. So the students drew their hummingbirds and flowers breaking them down to simple shapes and then outlined in sharpie. Then they made many paint puddles and worked wet on wet to paint each "piece of glass".
