This cotton batting is a non-allergenic, natural cotton batting that’s made with the finest, clean, natural (unbleached), long-staple, virgin cotton available. It should be paired with medium or dark fabrics. If paired with white or light-colored fabrics, natural (unbleached) cotton can slightly darken the fabrics. We recommend quilters test this batting with their chosen fabric(s) to see if 'darkening' will be an issue.Details:120" x 120"Shrinkage of 3-5May be stitched up to 4" apartHypoallergenic100% cottonMachine washable
