Hobbs Heirloom® Premium 100% Cotton Batting is a non-allergenic, natural cotton batting that’s made with the finest, clean, natural (unbleached), long-staple, virgin cotton available (and it proudly displays the Cotton Incorporated Seal). Should be paired with medium or dark fabrics. If paired with white or light-colored fabrics, natural cotton can slightly darken the fabrics. We recommend quilters test this batting with their chosen fabric to see if ‘darkening’ will be an issue. This batting may be stitched up to 4" apart, and it is needle punched with no scrim.Details:45" x 60"3% - 5% estimated shrinkage expectedMachine washable once inside a quilt. 100% cotton
