After I glazed the yellow over the green cloth area, I noticed that it obscured the underpainting beneath much more than I had anticipated. If I went ahead as planned and glazed green over the yellow, much of my drawing would become nearly invisible. I decided to wait to put on the green, and instead, glaze in the darker shadows, since their borders define the lines of the drawing beneath. I would have glazed these darks as my next step anyway. After this dark glaze dries in a few days, I’ll finally be able to glaze the green over all areas of the cloth.
I also painted in a rough approximation of the colors of the stones. I didn’t touch the areas adjacent to the cloth, because they would smear as I work on my green glaze at my next session. A layered approach requires patience!
