WebDeco Linen is our most popular surface finish, a classy, timeless pattern with beautiful reflection behavior. By removing the distinctive linen thread, we created the less directional and more even version: Deco Linen without Slubs. Both types of Deco Linen are available in a scaled-down version for a finer and denser appearance.
