The natural course structure and characteristic rustic colours make it particularly suitable for large-sized (art) books. Flax fibres in our materials, Halflinnen Dark and Halflinnen Light, are certified under the Masters of Linen standard which means that the fibres are 100% EU grown and scutched. Masters of Linen stands for sustainability, European skilled jobs and social ethics. All flax under the regulation is sustainably grown - respecting the environment to achieve high-quality fibres.
