Why use "Soft and Stable"? It is superior to batting and other stabilizers. Made from 100% polyester foam, approximately an 1/8" thick, covered on both sides with black polyester fabric, it can easily be quilted or just sew around the edges of the pieces. Your project will have a professional "finished" look, no slouchy fabric or wrinkles. Very lightweight and maintains its shape even after washing and drying. The perfect choice for purses, bags and other craft projects!
