Did you ever have any of those children's activity books where they had pictures colored with dots, and you activated the paint by painting them with water? I had those and I found them very fun.
Recently I started using watercolor crayons. Using them feels like a cross between wax crayons and oil pastels. They are water soluble though, so painting them with water activates the colors and turns them into watercolor.
The fish painting uses water color crayon and colored pencils and then it's painted with regular water colors in the background. The lines are done with black colored pencil.
The tiger lily painting was done with colored pencils first. I did detail pattern work on the tiger lilies and the background. Then I colored them in with the crayons and painted with water.
The tiger lily painting took way to long with that background! It's a learning experience.
