Stunning silk satin with cotton content. The sheen is outstanding and, although it is "floaty", it still has good body and is easy to work with - much easier than pure silk satin. Unfortunately, this fabric is limited and I bought all I could get because I know it will be wonderful for dolls! I used this type of fabric for garments in the GCP # 3 project! It frays much less than pure silk satin and doesn't roll up when you cut it.
