I am really impressed with how easy these tiles go up. The instructions said that we might have to secure them somehow but that was not the case. We applied the glue and started sticking them up. It went pretty fast. I was floored. I was wondering g if I was going to have to use something for tiles to stay but they stuck great to our textured ceiling.  It gives our livingroom a great new look. I have to order more we don't quite have enough but I am loving how beautiful and easy it was. Since we did have a fire this was a great way to make the house look awesome again. Thank you very much.
