I have used it in larger projects and it has been successful. I used Hobbs 80/20 fusible. It takes some care in getting the sandwiching done. I used a few safety pins to stabilize the project and worked from the center out to the edges and it worked nicely. I stitched around the perimeter of the quilt to keep the edges from pulling apart with all the handling. The bond is adequate but it will pull apart-which is a good thing-in case you get a bubble. And, it seems to wash out completely when the finished product is washed and blocked. I personally like it. I do not like polyester batting so I cannot give an objective opinion about that fusible.
