Heirloom Premium is wonderful to quilt by hand or machine. This blend is made with 80% natural cotton and 20% fine polyester. It is needle punched and has a light resin bonding to provide exceptional strength and durability. Close quilting yields a flat low loft appearance while more space between stitching lines yields a slightly higher loft. You may experience shrinkage of 3-5% and it may be quilted up to 4in apart.
