I have used the batting tape for 100% or 80/20 just a couple of times, poly batting I sew in a cross hatch method, have also done this a few times. I've measured and labeled all my scrap pieces and have made table runners, table toppers, hot pads and place mats with the smaller pieces, for the larger pieces I look in my MANY patterns for one with that approximate size and make that pattern. I have the scrap pieces in small plastic "boxes", with a scrap piece of paper on what sizes are in that box. I have made progress in using pieces but unfortunately, still have a lot to go. LOl
