Ideal for your quilting and other fabric projects, The Warm Company Warm & Natural Cotton Batting does 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. This needled batting’s flexibility makes it ideal for both inside and outside use. Its fibers are held together without glue so a quilting needle easily glides through this cotton batting. It can also be used as an exterior fabric and for quilting up to 10 inches apart. Easy to dye, your fabric will cling to the batting while quilting.
