I have used the Hobbs 80/20 fusible. I really like it but it is flatter than some batts. There are some issues but I prefer it to pinning. I machine quilted a twin bed size and it worked well. (no puckers) It feels really flat when ironed but did puff up a little when washed. You need a big surface to iron it on to get all the wrinkles out.(used the floor) I also re-ironed the back halfway through to smooth any extra fabric to the sides. Do not use steam because that removes the fusible.
