Textile, Fabric, Textures, Patterns and Cloth Design Golden Butterfly with Pearl Silk Quilt by Yunhui Cao Golden Butterfly with Pearl is a silk quilt designed for modern bedrooms. The filling is made of 100 percent double cocoon mulberry silk, and the outer shell is made of natural silk, giving a light and warm feel. The cover is embroidered with butterflies, and detailed wing veins, colored pearls and fine stitching create a three dimensional surface. A removable inner shell replaces traditional quilting, so the quilt is easier to clean and maintain. The design is themed on metamorphosis, an Eastern image of change and renewal.
