This is a shot of my entire set up. I prepare my canvases with two coats of Gamblin's Oil Painting Ground. I rough it on with a big palette knife and get it fairly smooth, but not perfect, I like some imperfections. I stain the canvas with a combination of warm earth reds and when it is dry sketch directly with thinned paint. Lately I've been using Winsor Newton's 'Drying Linseed Oil' as a painting medium.
