I have a hand-me-down sofa and chair that are leather made by Viewpoint Leather Works, it is about 16 years old. Under the cushions are velcro stabilizers and they have worn out I guess because they are no longer holding the cushions in place. I have tried to buy industrial strength velcro to replace it, but nothing will hold! Any suggestions? It is really annoying and I want to fix it ASAP! Thanks in advance for any suggestions, especially if they work
