I AM CURRENTLY INVOLVED WITH MAKING POLYESTER QUILTS FOR THE HOMELESS.I HAVE SCADS OF 54 TO 60 INCH HEAVYWEIGHT KNITS.LEFT OVER FROM THE BEGINNING OF TIME.I BELIEVE I HAVE ENOUGH FOR 30+ TWIN TO FULL SIZE QUILTS.SO FAR I HAVE USED BLANKETS FOR THE FILLER .I ALSO HAVE LINED SOME WITH SHEETS AND USED LIGHT WEIGHT COTTON BLANKETS FOR FILLER.I AM NOT PIECING THEM BUT I AM MACHINE TACKING THEM FOR DURABILITY.ANY OTHER SUGGESTIONS FOR FILLER WOULD BE APPRECIATED. I RETIRED 2O YEARS AGO AND AM JUST NOW GETTING AROUND TO CLEANING OUT THE ARCHIVES.
