While some think fleece is too expensive to use as batting, remember that because it's encased between the top and the backing, you can use the cheapest stuff available. (I have a "Mill End Textiles" near me where I bought a remnant at ~$3/yd.)
Do you use batting and fleece together to make the quilt warm or do you just use fleece? I would like to make myself an ultra-warm quilt.
