Agree as well ... if it's really that loopy, the bobbin thread should pull right though then all you need to do is pick up the top thread.
As for quilting it again ... yes certainly get out some practice sandwiches. I do this with every single quilt. I test the thread, the needle, the tension to make sure everything is compatible. If the whole thing is loopy, it sounds like a tension problem so should be easy to fix with the top tension (increase it).
