The cartoon can be considered the pictorial paper pattern of tapestry, made in real size.
It is possible to find “grisaille” or sepia colours but the most part of those we have received in our time are painted with oil or watercolour on paper or canvas. The pattern is often accompanied by written notes or comments left by the painter “Cartonnier” to guide the master weaver. It is also the “upside-down” version of the original work and tapestry.
