I have never used that brand before but what is the method for fusing? I use Hobbs 80/20 fusible and it is water solvable so no steam on it or you run the risk of losing the fusible. Sometimes it has wrinkles in it and I carefully separate the folds and smooth it out. When I dry iron my sandwich together, if any bumps remain, I gently pull them ahead as I iron the sandwich flat. I iron both sides of the sandwich and make sure it is wrinkle free before quilting. With the Hobbs you can peel it back and refuse if needed. Does your fusible allow that?
