One of the classes I am taking over at Art Tutor is about watercolor pencils. I bought a while back 10 Inktense pencils and I seldom use them. I also have watercolor crayons - and I use them even more seldom that the pencils.
I also think that they might be a better choice for sketching out - at least for now. They are easy to carry around and I can use the water brush. When I will get better and faster with watercolors, I will take them out again.
Inspiration - a photo taken in Girona. I am pleased with the result. Different from pure watercolor washes of course, but not bad. What do you think?
