Sketchflow is a project template type that can be created to quickly prototype application design, quick UI experiments, and communicating design intent. I decided, to get a bit more practiced at using the Sketchflow capabilities, that I would write a quick tutorial on starting and creating a basic Sketchflow Application. First step, open up Microsoft Expression Blend 3. Then click on File and then New Project. In that dialog you will see the available Expression Blend Project Templates.
