I feel your frustration. When this happened to me on a baby quilt I added a new back. I put a very soft fabric on the back and sewed all sides and turned it inside out. It ends up like two blankets sewn together. You don't see the quilting from the back only the front. The baby loved it because as she got older she could scrunch it up with the loose fabic. In fact I have made several this way since then. Just another option other than trying to get it out. good luck
