For a long time watercolour artists have had to make use of acrylic mediums if they want to experiment with texture.  Now Schmincke has developed specific molding pastes to use with watercolours.  The real benefit of this is compatibility, watercolour can be used with these pastes knowing they are designed for watercolour paint and are of artist quality. The watercolour paint will attach to the molding paste successfully, keeping their lightfast and long lasting properties.
