Is Hunan embroidery mounted with glass or film?

Hunan Embroidery Mounted Glass. Xiang embroidery is often mounted with glass instead of film. This is because glass has good transparency and hardness, which can protect Xiang embroidery works from damage and has beautiful effects. Xiang embroidery works usually have high artistic value and collection value. If it is mounted with film, it is easy to make the work lose its original artistic effect, and the protection and aesthetics of film are not as good as glass.
