Essex Linen and Essex Yarn Dyed Linen by Robert Kaufman Fabrics. 55% linen and 45% cotton mix. A perfect weight and drape for light home decor projects, bags, dress-making, applique backgrounds and quilts. The Essex Yarn dyed fabrics have a heathered look because the yarns are first dyed, then woven into fabrics. The staple Essex Linens are piece dyed – the yarns are first woven into fabric, then bleached and dyed into colours.
