Here are some books I've found helpful:
- Painting with Children by Brunhild Muller -- very good detailed instructions; a little more Waldorf-y than I like (includes poems to unleash the creativity within) but the information is worth getting the book
- Watercolors: for the Artistically Undiscovered (Klutz) by John Cassidy -- just fun to use; many of the pages are watercolor paper so you can do the exercises and play right away (including watercolor paint).
- Watercolor Basics: Let's Get Started by Jack Reid -- don't be put-off by the cover; this book is a gentle tutorial on watercolor painting. Reid has taught for many years, thousands of students how to paint gorgeous watercolor like the cover image!
- Watercolor in Motion: How to Create Powerful Paintings by Birgit O'Connor -- now here's a great one because not only is there a spiral-bound books (I love spirals as you can lay the book flat without worry) but she has also done a 50-minute DVD so you can SEE what she means. I really liked this one and the kids learned alot.
- Fine Art Studio: Watercolor by Mary Iverson -- like the Klutz book mentioned above, ths is a full kit with paints, watercolor pencils (which are so fun to use), watercolor paper and a mixing palette (altho you can use any shallow, plastic plate just as well). This one is geared for kids and includes work examples by Beatrix Potter -- one of our favorites. The recommended age is 10 but there is no reason that younger kids (with adult help) couldn't do the 40-page book!
