I used to use this batting almost exclusively, and for large projects too. It is a bit of a pain to fuse a big quilt because you need a very large space where you can lay it out AND iron it. My living room floor was perfect. I used the really big T-pins to pin the backing directly into the carpet. Then I'd lay out the batting and smooth it flat and pin it. Then do the same with the top. I would sit in the center and start pressing from the center out. After I'd gone over the whole surace, I would flip it over and press the reverse side. I used safety pins just to hold the outer edges in place. If it started coming loose as I worked, a quick press with the iron would fuse it in place again. All the stiffness from the glue washes out. And it seems to wear about the same as the regular 80/20. The only reason I don't use it as often is because the price went up. Since I started making things to sell, I buy the big rolls of Warm and Natural since it's more affordable for me.
