Quite a few quilters hand quilt Warm n Natural. It is needlepunchd through scrim, and this makes it harder to hand quilt than battings that are just needle-punched (such as Quilters Dream Request cotton, which is very easy to hand needle).
Try it and see how it works for you. Have you hand quilted before? The very first quilt I hand quilted, I used a very traditional cotton batting that I later learned is much harder to hand quilt than QDR. At the time, I just thought that was how difficult hand quilting was supposed to be!
