Poly-Down is made with very fine white denier polyester that provides a lovely soft drape and makes this batting exceptional for hand quilting. Poly-Down is resin bonded to provide added durability and resist bearding and migration. It is machine washable, non-allergenic and maintains loft. This batting may be quilted up to 4” apart and will not shrink. We recommend that the quilt maker spend some time learning about this product before using it on a major project. Make samples using this batting to see how it launders and how it needles, both by hand and by machine, so that you can obtain the look you want in your final project.
