I used fleece for batting inside of my Christmas Tree Skirt ~ it worked great, just had to make sure to start in the middle (hole for tree) and work outward... it did stretch a little, but I kept-a-smoothin' and it worked fine. Drapes really nice, too. Used it in a small lap quilt for kids, they say its super duper warm, but its heavier than all my other quilts.
I would not recommend it for use in anything more than a lap-size quilt because of the weight.
