Sunday! Free day at the Oakland Museum and a chance for about 35 sketchers to descend on the special exhibit, “the Rise of Sneaker Culture.” For a change of pace, I went downstairs to the natural history section, where I improvised a composite of California wildlife. Using my new Stillman & Birn softcover sketchbook. I found out that I’d better stick with the hard-cover series, because I work standing up with no support for my drawing surface.
