Texture is the surface finish of a particular paper and often becomes its fingerprint. Sometimes texture is called the “tooth” of the paper. Texture can dictate which medium should be used on that surface. For instance, pastels and charcoal work best on rough-textured papers, especially when applied in multiple layers. Pen and ink work best on smooth papers, specifically if metal nib pens are being used. For the most part, texture is a personal choice for the artist and part of the creative process and artistic expression.
The terms used to describe texture can be confusing and sometimes cryptic, especially since there are no standard descriptions. Textures are unique to the manufacturer and vary according to the medium. Therefore, it is advisable to collect paper swatch books to keep as reference for future paper choices. You cannot determine if a paper texture will work for you until you use it and experiment with various techniques and mediums.
The gritty, granular sanded pastel paper surface holds the pastel strokes. The inherent texture of the paper plays a part in the final feeling of the painting. Mounted pastel paper helps keep the painting flat, especially when wet techniques are used.

Paper can be used for all mediums except oils because the vegetable drying oil used in oil paints is acidic and will eventually destroy the paper fibers. If you are using oils on paper, it must be primed with additional sizing such as hide glue or an acrylic ground like gesso. However, there are canvas-textured papers that are suitable for oils because of the coating. Arches Oil Paper is a relatively new paper that can also be used with oils without preparation. It is specially formulated with a barrier added to the pulp during manufacturing that protects the cotton fibers from acid.
