Winsor Newton Davy's Gray outlines of the coins and of the centers of each button (two circles for each button), layering in the button colors, painting in the "threads" two or three times, painting an outline for each button and center, and then stopping to count. When I was certain that I was half finished, I found that I had painted far more than 100 buttons, and that I certainly was nowhere close to being finished.
The story of the formerly nameless traveling nano is grows more like 100 Buttons every day. I drew the nameless shapes, painted both the shapes and the little links that connected them with Winsor Newton Davy's Gray, painted the colors into the shapes, outlined each of the shapes with Daniel Smith Deep Sap Green, and painted colors into the links between each of the shapes. For the two days that I worked on the little links, I thought that they would perform their linking function without an outline between the between each shape. Although I haven't (and won't) count each shape, it is clear to me that each of the little links needs an outline. And yes, there are far more little links than there are "big" shapes.
This is quintessential Painstaking Exuberance. Gotta outline. Gotta get to work.
