Starting an Oil Painting
Although my stretched store-bought cotton canvas is already prepared with gesso, I add 3 more layers with a light sanding in between each. This makes the canvas less absorbent in my opinion. Everyone has their own recipe and this is mine. I apply the gesso with a roller if the canvas is big or a large brush if it is smaller.
Once the gesso is dry, which is within the hour of the last coating, I use vine charcoal to outline my composition. Because the charcoal is rather dusty, I blow the excess off using either my breath or an aerosol can of dust remover depending on the size of the canvas.
Next, I then use a thin wash of burnt umber paint and a thinner medium to cover the rough charcoal drawing and begin the shading process. This also fixes the drawing to the canvas & prevents the charcoal from blending further. That layer will dry, depending on the medium you choose, in an hour or a day. I then begin another coat of underpainting using either a warm or cool brown or gray base color. This can either be considered an underpainting or if more detailed and finished it would be called a grisaille. Over an underpainting, I would paint using opaque pigments and over a grisaille, I would be using transparent pigments for glazing.
Once this is dry in 1-4 days depending on the mediums used, I then begin painting with color. This is the very classical beginning to an oil painting that I was taught by my professors during my college years in another place and another time. I’ve always been glad that I was able to receive a formal Art education and it has been the basis of all my work over the years.
