Depending on how you're doing the actual quilting I would not recommend 2 layers of W&N. Did that once and hand quilted it - painful doesn't come close to describing THAT experience. Now, if you're machine quilting, it might be okay. I've had recipients tell me that the quilts I've made for them - regular cotton front/back and one layer of W&N for the batting were surprisingly warm. I did make one for my niece with a flannel backing as her room is very cold in the winter. She's only 9 so hard to say if she really finds it warm enough but supposedly that is the case.
