After many months of avoiding it, I finally got back to working on the mural. I picked up four more sample jars of paint- green, yellow, brown and a bluish white- and a couple narrow rollers.
I have a lot more do to but I'm pleased to be making some progress after months of inactivity. No particular area is "done" since I prefer to build it all up together. I'm trying to treat this like any other painting and stick to the "techniques" I'm already familiar with. You know, except for the fact that my canvas is 10 feet across, my paint brushes are huge (or paint rollers) and my paint comes out of jars and gallon buckets rather than tubes. So far so good!
