I start these by drawing a basic sketch on watercolor paper. Then I draw patterns and some details with colored pencils. Next I take the watercolor crayons and put some color and shading in.
Tomorrow I'm going to do the next step of using watercolor on top of these. That will make all the crayon parts turn into watercolor. I could just use water but I like to experiment with just a little more color. I may put in some metallic detail with acrylic paint, and then ink the outlines in.
I like this technique because I can do the first part in my home office at my desk. There's no water to spill! I will do the rest of it in my studio upstairs where the cats are not allowed.
It's also really fun to get the paintings to this stage and then see what happens to them when the water is applied. It feels magical.
