Heirloom^® Premium Cotton Blend is made from 80% long staple cotton fibers and 20% fine polyester. This combination of fibers creates a strong, longwearing batt and is very easy to handle. The batting is lightly needle punched and treated with a soft resin to provide stability to the fibers and prevent the polyester from bearding. This process makes Heirloom^® Cotton Blend Batting uniquely easy to quilt by hand.
