When working on commissions I only use Arches Aquarelle watercolour paper, it is a joy to work with. I like the Satine finish as it keeps the ink line beautifully steady. This paper has been made in France in the same mills since the 1400's. I love the quality and believe it is worth using the very best materials to create a piece of art. It contains no added brightening agents and is acid free, for longevity.
