Saturday's Sketch

"Big Walnut," wc/ink, 12x5

Despite the unusual heat here in the upper midwest, our group of sketchers went out as usual. A group came to my home studio where we fanned out along the creek under deep shade, where it was marginally cooler. 

This little watercolor was the result for me. One of our group took a folding chair and sketched under a giant black walnut tree. I was interested in the tree and its bark, so I sat in even deeper shade and did this one. As I usually do, I made a preliminary sketch in pencil and then painted the image with watercolor. One of the things about many watercolors one sees is how washed-out the darker values can be, so I worked hard to make my dark greens rich and believable and the tree bark varied from very dark to quite light. My initial plan was to use only paint, but after the watercolor was dry it seemed to need something, so I added grooves and ridges to the bark with ink.
