When selecting a substrate, it is crucial to take into account its compatibility with water-based or oil-based (dry) materials. Water-based materials necessitate a substrate with a certain level of absorbency. This allows the substrate to soak up moisture from the surface and permeate it, which can cause it to warp and distort. Consequently, thicker paper is less prone to bending and possesses greater load-bearing capacity. Once the substrate has been determined, the adhesion of the paint will augment the artwork's thickness and create a sense of layering, ultimately enhancing the quality of the texture
