I absolutely LOVE to use fleece as backing with flannel quilt tops. The ones I have done are tied not free-motioned. They are snuggly in the chill of winter and they are the favorites of all my family. And, I don't bother with batting when I use fleece. My favorite one to do is a rail fence...I put the top together with my serger...lay it out on the fleece and tie it. Really a quick project for me.
