I used the 'Fusi-Boo" by Fairfield on a small wall-hanging. It made the piece rather stiff, wouldn't like to use it for a larger quilt, but was easy to handle for machine quilting. The stiffness washed out when I was finished. I have a (double-bed size) quilt fused with Hobb's 80/20 fusible that I haven't started to quilt yet, but I think I'm going to have to pin at least the edges since it really hasn't stood up to handling very well and I'm doubtful about all the manipulation it will need for machine quilting. A friend used the June Taylor fusible batting for a table-runner and it just tore apart when she tried to reposition it.
