One of the most common mistakes in watercolour painting is using the incorrect paper. In order to keep your surface from absorbing too much water, you will need high-quality watercolour paper, with a high GSM of at least 300. Watercolour paper is available with a variety of surfaces and sizes, from the smooth Hot Pressed to the textured Cold pressed (NOT) and Rough varieties. Shop a wide selection of Watercolour pads, blocks from the top brands, such as Arches, Winsor & Newton, Bockingford, Saunders Waterford, our artists' quality Cass Art Collection and more.
