This small still life really did start out as “finger painting”.
I often start a painting by putting down a colored gesso as my base to paint on, usually orange. But in this case I used a light wash of red oil paint, thinned out with some odorless mineral spirits. To do this, be careful to not get the paint so diluted that it actually runs, just thin enough to lift off easily. The panel I used is an Ampersand gessobord which is ready to paint on.I covered the whole panel with a light coat of red, then used a soft cloth over my finger and pulled off the shape of the glass and bottle, especially the high light areas. After that I mixed up a slightly thicker blue to put in the dark outlines and shadows, still mainly using my fingers and a soft cloth.
With this paint being thin and wet it is easy to make corrections to shapes at this time, and really what I am looking for at this point is the over all masses of the composition.
I let that dry over night and the next day finished the painting, this time using a brush and thicker layers of paint.
