Although materials of hanging textiles are not as striking and intuitionistic as color and pattern, materials of hanging textiles have their unique and subtle artistic effect, and have great influence on style, modeling and performance of indoor decoration.
Different materials bring different aesthetic experience.
On the other hand, a variety of materials should be used to reflect the technical aspect of hanging textiles’ decorative beauty.
