Love the way the 3D wall panels look. However, I had a difficult time getting them to stay up. First, I used silicone and the edges starting coming up. I tried double sided tape and I had the same issue. I even tried a brand of heavy duty construction adhesive it worked better but I still wasnt getting the results I wanted. The only thing that worked without fail was the Gorilla construction adhesive and I used my adhesive gun. The panels were  easy to cut with heavy duty scissors. I love, love, love the look. Save yourself some time and purchase the Gorilla construction adhesive. Any other brand will not yield the same results. Thanks to the person that mentioned this in their review, you saved me from ditching this project. Also, great price for these panels. I saw something similar in the store and it was 22 per panel. Yikes! Thanks Wayfair!
