This work has its origins in those random and deliberate brush mark developments. I love those shapes. The following relates in particular to the ones in the lower half of that earlier post.
Wanting to put some reference to my body in the work, I worked out a way to use my reach. I planted my feet in a spot close to the wall, near the corner and used one hand only to paint. I began to build the shape with the aforementioned random brush marks, but only what I could reach with feet planted. The arc of my arm meant the shape took a circular structure.
