One of the watercolor projects from Chapter 1 in Anne Elsworth's book (Watercolor Skills Workbook - 10 easy lessons) is mixing watercolors to match master paintings. I chose this Picasso piece (which was done in pastels) and used my regular palette of primary watercolors to mix each of the colors that I could see in the print. This is a fabulous way to train your eye and I hope to do more of these projects as I work through her book.
I am now done with the projects that I want to do from Chapters 1 and 2 - and ready to move on. I need to plan my way through these exercises and projects slowly if I want to enjoy them. I think I was previously unable to appreciate the 10 lessons because I was trying to rush through the book.
