Its acoustic properties and understated elegance have made Grain a popular fabric. The sound absorbing curtain is based on various colours of contrasting yarns which together create a shimmering outward appearance. Its construction gives it a clear structure which contributes to the beautiful drape. Grain combines a sensation of softness with a sophisticated image and contemporary colour scale. This fabric enjoys widespread appreciation and is easy to combine with other textiles. Use it as a classic window curtain or to create new spaces for interaction.
