Hobbs Poly-Down Batting is made with very fine, white, denier polyester which enables this batting to provide a soft feel and lovely drape. Exceptional for hand quilting, it is also prized by machine quilters for its wonderful loft which accentuates quilting details. Hobbs Poly-Down Batting is bonded to provide added durability and resist bearding and migration, and its machine-washable, non-allergenic and maintains its loft. Items made with Hobbs Poly-Down Batting may be machine washed – we recommend all quilts be washed using a delicate cycle and cool water, with no heavy agitation or spinning. This batting may be stitched up to 4″ apart and no shrinkage is expected when the finished project is washed according to our care instructions
