I'm a longarm quilter, so I deal with lots of different kinds of batting. I can spot a quilt with polyester batting from a mile away. It looks like something from the 1970's, which is not a good thing. Plus, lots of polyester battings are uneven in consistency, so you end up with thin areas with hardly any batting in the middle. I highly recommend a cotton/poly batting with mostly cotton, like Hobb's 80/20 (80% cotton and 20% polyester). Warm and Natural is too warm, in my opinion.
