I actually prefer poly for my quilts in the northeast. They are warm in the winter, easy to hand quilt and don't wrinkle when stored. Also, comfortable on my wallet. I love Hobbs Poly Down. Have quilts that are more than 20 years old that have this batting and have held up well through much use and frequent washing. I purchase mine through Connecting Threads when they have their 30% off sales a couple times of year. They are wonderfully warm without feeling heavy.
