But I did manage to document one spread in detail. It's one of those happy cases where the very first tiny sketch, done for the storyboard, remained basically the same throughout the work. Here it is as a 1 x 2 inch doodle: Beatrice and Bear saying goodnight and going sleep:
Next came a larger sketch, better suited for the dummy, done with a bit more detail:
I sometimes photocopy pages from the dummy to test colors -- the paper is not really suited for watercolor painting, but it helps me to see whether the colors I'm envisioning work or not and to try different color combinations:
Now for the final painting, which was done on Fabriano 140 hot press paper. I used a light box to transfer the sketch to the watercolor paper, and did the outline first, with a brush and Winsor & Newton black India ink. I erased all pencil marks and then started painting using Sennelier watercolors and Prismacolor pencils to add texture and/or shading.
