I've taken a number of painting classes over the years, and I believe this is the first time the instructor has taken the time to have us get familiar with the tools and their capabilities to such length before we actually get started on the primary subjects. Although I'm new to water-brushes, I am comfortable with watercolors, acrylics and oils--and I've still learned something new. Good practice! I can't wait to use the techniques we're learned on birds. Thanks, Jane.
