I rubbed a sticky substance called Liquin over the entire canvas in a very thin layer with my index finger. I used a bristle brush made from the hair of a hog and rubbed vermillion red onto parts of the babies face, fingertips, and toes. I rubbed a mixture of vermillion red and raw sienna onto the adult arms and fingers. I blended Prussian blue into the dark background and then I smoothed all of it out with a dry red sable brush.
In this early stage, there is very little color. Luminosity builds with each successive layer, transitioning from from light to dark, and cool and warm colors.
