Arches Watercolour paper is crafted from 100% cotton for exceptional strength, stability, and absorbency. Each sheet is mould-made and traditionally gelatin-sized, giving artists beautiful colour vibrancy, crisp handling, and the ability to withstand heavy washes, lifting, and repeated working. Available in a range of weights and textures, Arches offer a professional, archival surface trusted worldwide for watercolour, gouache, ink, and mixed media.
