“tooth” as opposed to hot-pressed paper which is very smooth. Rough paper is available but has pits that can grab your brush and create pockets of color.
Masking
Watercolorists traditionally paint whites by leaving the white of the paper. To do so, these areas need to be protected from being painted inadvertently. This means you must plan ahead for where those areas are going to be and take care to not paint over them by mistake. An easier way to handle this is to mask them with pieces of tape or masking fluids. Masking fluid is applied with an old, worn-out brush (never a quality or new one) to those areas that are to be protected then allowed to dry. To remove the mask, rub it gently with a clean dry finger or rubber cement pickup.
