FYI- I was just quilting my hexagon table topper and i'd put Deco Bond 809 on the back of it. My needle seemed to not want to go through it and I took it out and turned it over. I hadn't put the backing on it yet and could see the fusible. there was a one inch disk. round as could be. evidently it was some fusible that gobbed up in the processing and got flattened out. I had to get it unstuck from my fabric and cut it out. Got it!! Then continued to quilt. From now on, I will inspect my fusible before putting it onto my project. All's well that ends well.
