Hobbs Heirloom® Premium Natural 100% Cotton Batting is designed for quilters who prefer using a natural cotton batting, and for those who want a traditional looking quilt with a fairly flat finish and exceptional softness (it gets softer with each washing!). It is a non-allergenic, natural cotton batting that’s made with the finest, clean, natural (unbleached), long-staple, virgin cotton available. This batting may be stitched up to 4" apart, and it is machine washable (once inside a quilt), with shrinkage of 3-5% expected.
