A mixture of 20 pieces of different silk fabrics. Please note that the exact mixture may not be as shown in the photos, but I try to make the mix as interesting and inspiring as possible! They vary a bit in size but the average size of each individual piece is about 4" x 4". If you've ever wanted to explore kimono silks, this is an affordable way to get a real introduction. They are also a great gift idea for a friend who sews patchwork quilts!
