The types of pastel materials that I enjoy using most are "dry" pastels that have a variety of textures from gritty to silky smooth. Using a range of color materials and substrates allows me to create visual texture and layered depth of color. This process inspires me to create a dimensional approach to what is called "pastel painting."
But in the way I work, some of these techniques are related. Pastel has a definite relationship to monotype when those pieces are layered and include pastels--and in the same way is realted to mixed media. Of course drawing is in the mix also, often in an abstract way! And the inclusion of the word "painting" in this medium just refers to the effect of the work being painterly, whether it is realistic or not.
