This material is not 100% silk, I don't know what percentage of silk it has.
Silk Habotai fabric is the type of a plain weave silk cloth renowned for its fineness, light weight, softness, sheen and silky hand. All-natural, it is most commonly used for lining, as well as for creating summer blouses, pareo, light lingerie and scarves.
This Black Habotai 60" is soft and lightweight, this is a kind of smooth fabric and has a beautiful drape and smooth surface. It has less sheen than silk and is very inexpensive when compared to silk.
