oh fusible batting! i've used it just fine. Hobbs heirloom 80/20 fusible. with all batting that comes in a bag all rolled up, there are areas that are stretched a bit. hate that. but otherwise it's fine. i lay out my backing, batting and top.then start in the center and iron/press. then move quilt and do the sides. (i do this on a joann's folding table). then turn over and smooth the backing again and iron/press it in place. i tend to pin the edges for handling under the machine to quilt it.
then when done, i soak the quilt, spin out, soak again and spin. then dry.it's soft after that.
