I use the Edge Perfect Blade and really love it...you just line your ruler up with the edge of the fabric and run the blade where you want to make perfect slits. I don't think this is what you're asking but thought I'd throw it in here for another choice for you to edge fleece blankets. You then can do your blanket stitch, crochet stitch or numerous other types with yarn, embroidery thread or whatever you desire for a really nice edge on your fleece blanket.
