Although "silk" is a common term used to describe artificial botanical, flowers and foliage, their floral designs are actually made of materials that have more durability and do not fray or fade as silk does. Particular botanical components are individually wired and specially crafted to maintain realistic form, while the subtle coloration, shadings and striations in the natural botanical are duplicated to perfection! Cleans easily with a duster or dryer on cool setting.
