Rough grain paper (Rough)
This paper has a substantial tooth (indentations), which you can see here. For washes it requires brushes such as mop brushes and hakes, which can hold a lot of paint and water. It is not suitable for fine, detailed work. It is good for expressive art where you want to be spontaneous and bold. The paint can go into the indentations and cause sedimentation/granulation. This means clumping together of certain paint colours. The blues and browns do this best. The colours sink into the indentations (tooth) and give the painting a textured effect
Paint can also be dry brushed over the rough paper surface to create white ‘sparkles’ where the paint doesn’t go down into the indentations at all. This is especially effective if used to represent light on water. To dry brush in other areas that have already been painted, for example grass, cliff faces, bark on tree trunks, anything that requires a roughlooking texture, it is best to use a flat, square, synthetic brush as it holds less water. Lifting off often causes a mess on Rough Grain paper because the paint has receded deeply into the indentations. This paper is my personal favourite and offers great outcomes
