You will get lots of answers here. As a long arm quilter I personally hate Warm and Natural (it's like quilting through cardboard) but will use it if a customer brings it to me. I've used Hobb's and Quilter's Dream and have been happy with them but am going with Pellon Legacy brand of battings - love them! I will not use Fairfield or Mountain Mist products in my long arm business. Good luck experimenting and trying out what you like and don't like!
