A farmhouse in shadow, oil on paper, by Joseph Mahon

 I used gessoed heavy watercolour paper here as the substrate. When a watercolour does not work and is heading for the reject bin, I use the quality heavy paper, give it a couple of light coats of clear gesso and it's ready for use with acrylic or oil. This painting, oil on paper 7x10 ins, is a study of a field with the grass just been cut for silage and the farmhouse in shadow. Palette knife and brush.
