So what I ended up using to stick them on took about 1 hour to put on my wall… I used Velcro! I was a little confused as there were no instructions or adhesion and I don’t like to damage my walls ever, but it worked fantastic. Also for some reason I thought there weren’t suppose to be any groves in between every panel… but that’s the design and I like it … I’m totally impressed and it gave my tv wall such a hotel look!
