I just backed a baby quilt using Northern Lights fleece from Hancocks. I'm not sure what it's made of but it looks and feels different then the 100% poly fleece. It's not slippery at all, in fact it was hard to move my quilt around while doing the machine quilting. Also every thread and tiny piece of fabric that was on my sewing table got stuck to it...it was like a magnet! It looks nice now that it's finished but I'll never use it again.
