Any type of paint is suitable for use in paintings portraying texture: it is the way in which it is used that determines whether or
not the painting is successful. We look at watercolor, gouache, acrylic, and oil, occasionally mixing some of them together, as this can
produce surprising and exciting work.
You don`t, initially, need to use all the mediums mentioned. Perhaps start with one, explore its possibilities, and then move on to
another. Every medium has its own natural capabilities for producing texture—and its limitations—and you need to discover these for
yourself.
