I love wool batting; dream poly is also a nice batting. Poly battings are warmer. Flannel backings also add nice, cozy warmth. Fleece backing is another choice for really warm quilts. (W&N is my last resort, last choice for any project other than maybe a wall hanging) there are really many wonderful battings on the market to choose from. Visit *Batt Mart's* website where you can read about and compare the properties of many different battings
