Vermeer did not paint the "Girl with a Red Hat" on canvas. He instead, utilized a small oak panel (unique among Vermeer's works) which had already been painted upon. In the x-ray of the painting (left) we  perceive a bust-length portrait of a man in the style of Carl Fabritius, a fellow Delft artist.  His wide-brimmed black hat is easily discerned. We do not know exactly why he utilized such a support. In the inventory taken at the artist's death there were no less than eight prepared canvasses in his studio.

on primed ground



Through recent studies  it seems that Vermeer painted directly upon the old panel turning it upside-down. He then partially obscured the distracting white collar of the man with some brownish paint. This is the only documented case of such a practice. He normally primed his canvas with a mixture of animal skin glue, chalk, and a small quantity of raw umber, a brown earth pigment. He applied the priming with a pallete knife or a brush. Priming protects the underlying raw canvas and creates a smooth neutral surface which is hard but not brittle, it is ideal for the subsequent oil painting. Vermeer then used the finest sable brush and either umber or lead white to outline the principle contours of his composition. It would appear similar the illustration to the left. In a good reproduction of Vermeer's  Art of Painting  we can see that the painter, who is at the first stages of painting a portrait of a young girl, has already drawn the sleeves of his model in this fashion.
