I use fleece all the time as batting, pairing with it 505 spray since the fleece is usually stretchy in one direction. The 505 works to help with stabilizing the fleece. I've also used fleece instead of pellon in alot of bags and totes. Sometimes I will use the fleece in place of batting or pellon just on the lining of the bag, it just depends on the look and "stiffness" factor I'm looking to get with the tote. If I'm making a hobo bag or slouchy bags or make-up cases the fleece is fine, but if I'm making a bow tuck (that I like to have a more sturdy shape) I bypass the fleece and go with the more expensive pellon. Hope that helps.
