This batting will not separate, bunch or beard. This 100% USA grown cotton is punched with hundreds of needles through a thin base material (polymer fibers) to prevent tearing, shifting, migrating or creeping through the cover fabric making it 87.5% cotton/12.5% polymer fibers. Needled cotton's flexibility makes it ideal for both inside and outside use. Fibers are held together without glue so a quilting needle glides easily through the batting. What an incredible difference! No need to pre-wash, machine washable after quilted, can be used as an exterior fabric, quilt up to 10in apart, easily dyes and your fabric will cling to the batting while quilting. 90 inch wide batting. Made in USA.
