Tuscany Silk bonded batting is made from imported silk filaments with the addition of 10% polyester. It is then carded and resin bonded to help retard bearding (fiber migration) and allowing the batting to be handled like a blanket. It can be quilted up to 4″ apart and hand washed in tepid water and then laid out to dry flat. It will likely shrink approximately 5%. Because of silk’s natural ability to breath. It is an excellent choice for airy lightweight quilts and coverlets. The Tuscany Silk batting quilts magnificently by hand or machine and is a superb filling material for embroidery.
