Just wanted to add that there is a right and wrong side to fleece. To figure which is which, just stretch the fabric slightly. The fleece will curl to the wrong side.
I've never sewn garments with fleece, tho' I've made a lot of throws. I usually use a short zig-zag stitch, since it does have a stretch to it. Fleece won't fray, so either trim the seams, pink them or sew them down.
