So moving on from Wave, which was painted on a loose piece of canvas, this smaller work is on a stretched frame. Working by manipulating very runny acrylic paint and letting it dry between the application of different hues, I placed the stretcher on the floor by a window and, with the sun shining through, noticed that the mullions cast a lovely shadow which added depth to the painting. I quickly grabbed a brush and thinned Payne’s Grey and captured the shadow. Several layers later this is the end result.
