Techniques and Application
Gouache was applied as a wash with a Princeton Art and Brush Company 3/4" synthetic sable flat wash brush. Two different proportions of water to paint were used to achieve different degrees of opacity. A 50/50 mixture of gouache and water were used to create an opaque wash. A 10 parts water to 1 part gouache mixture was also used which produced a more transparent wash. The washes were applied in two ways. First, in only one direction using a horizontal brushstroke. Secondly, the wash was applied to the paper in various directions.
Brush
Gouache, with no water added, was applied with a Princeton Art and Brush Co. ½” synthetic sable angular shader brush to produce a very opaque appearance. Both a single direction brushstroke was used in addition to applying the paint in many different directions.
Overcoat
No varnish or fixative was applied to the gouache samples.
