Size: Crib: 45 x 60in (114cm x 152cm) Heirloom® Premium Cotton Blend is made from 80% long staple cotton fibers and 20% fine polyester. Commonly known as 80/20 batting or wadding. This blend of fibers along with a light needle punch, creates a strong, long wearing batting, that is very easy to handle. A super soft resin provides stability to the fibers and prevents the polyester from bearding. This process makes Heirloom® Cotton Blend Batting uniquely easy to quilt by hand. Shrinks about 3-5%, but can be pre-shrunk. It is best to hand or machine quilt about four inches apart. Heirloom® Premium for use with medium or dark fabrics. Note: If used with light colored fabrics, unbleached cotton can slightly darken white and pastel colors.
